INVESTIGATION: Ukrainian Drones in NATO Airspace — Tsahkna Says Yes, and an Entire Doctrine Is Turned Upside Down

"Not So Optimistic": How the Deep-Strike Attacks Have Changed Things for Putin

Tsahkna’s most significant statement on June 29 was not his acknowledgment of the drone incidents—it was his assessment of the effects of Ukraine’s deep strikes on Putin’s political morale. “The tone surrounding Putin has changed over the past two and a half months. It’s no longer as optimistic. The main reason is economic—because of these deep strikes.” This assessment—by a minister whose country hosts one of the most active foreign intelligence services targeting Russia—is a diagnosis of the effectiveness of Ukraine’s strategy.

The Russian economic context Tsahkna refers to is documented by independent sources. Ukrainian strikes have taken 50% of Russia’s refining capacity offline, according to Ukrainian and Western analyses. Moscow considered a ban on diesel exports but then backed down. Lines at gas stations have been documented. Russian oil revenues—which directly finance the war—have been impacted by a combination of Western sanctions and the destruction of infrastructure by Ukrainian drones. Tsahkna cites a specific geographical fact: “Up to 60% of oil exported from Russia passes through the narrow Gulf of Finland”—a route that Ukrainian strikes indirectly threaten by targeting accessible terminals and export facilities.

The Acceptability of the Cost: Estonia’s Strategic Logic

Estonia’s position on Ukrainian drones operating in allied territory is not a matter of recklessness—it is the result of a coherent strategic calculation. Tallinn is less than 40 kilometers from the Russian border. Estonia’s history with the USSR—occupation, deportations, forced Russification—makes the Estonian political class particularly resolute on the issue of resistance to Moscow. And Estonian intelligence—whose Foreign Intelligence Service (VSSE) is recognized as one of the most effective on Russian affairs in Europe—provides Tsahkna with firsthand information on the actual effects of Ukrainian strikes.

Tsahkna’s reasoning is clear: if Ukrainian drones that accidentally stray into Estonian territory are a direct consequence of Russian electronic warfare, and if those same drones are destroying Russia’s war economy and shifting the mood around Putin, then blocking this strike campaign to prevent drone incidents on allied territory amounts to serving Russia’s strategic objectives. The tactical discomfort is real. But the strategic benefit is well-documented. This isn’t recklessness—it’s clarity.

Estonia shares a border with Russia and has firsthand experience of Soviet occupation. When Tsahkna says that Ukrainian drones falling on Estonian territory are an acceptable price to pay for destroying Putin’s economy, he speaks from a position that few European ministers can authentically replicate. This geographical and historical proximity gives him moral authority on this subject that analyses from Paris or Berlin cannot match.

Sybiha’s Asian Tour: Japan, South Korea, Taiwan

On June 29, 2026, Ukrainian Foreign Minister Andrii Sybiha began a tour of East Asia—Japan, South Korea, and Taiwan—with the explicit goal of transforming Ukraine from an aid recipient into a technology partner. According to an analysis published by RBC-Ukraine on June 29, 2026, Ukrainian “drone diplomacy” is at the heart of this tour: Ukraine is offering its experience in drone warfare—interception, attack, electronic warfare, and maritime drones—in exchange for industrial investments and informal alliances.

Japan, which is legally prohibited from sending weapons to countries at war, nevertheless made its first contribution to the PURL program in May 2026 in the form of non-lethal military equipment. Japanese companies developed the Terra A1 interceptor drone in partnership with the Ukrainian startup Amazing Drones—a drone that was transferred to Ukraine in April 2026 for testing under real combat conditions. Japanese deputy ministers (Ayano Kunimitsu and Kenji Yamada) visited Kyiv to sign an action plan promoting private-sector cooperation. This industrial cooperation, made possible by changes to Japanese legislation on military technology exports, is reshaping the landscape of Asia-Ukraine defense cooperation.

The Taiwan-Japan-Ukraine Triangle: Remote Cooperation

Taiwan represents a special case in Ukraine’s drone diplomacy. There are no official diplomatic relations between Kyiv and Taipei—as Ukraine officially recognizes the People’s Republic of China. However, informal cooperation is active and well-documented: Taiwanese defense companies have opened subsidiaries in Eastern Europe to work with Ukrainian manufacturers. Ukrainian MPs visited Taipei for the first time in 20 years in 2025. Taiwanese humanitarian and technological initiatives are operating in Ukraine.

The geopolitical logic is clear to both sides. Nataliya Butyrska, an expert at the New Europe Center, puts it this way in an analysis for RBC-Ukraine: “We must ask ourselves what role we can play in the event of a conflict in the Indo-Pacific region. We need to start thinking about this now.” For Taiwan, Ukraine’s experience of resisting a neighboring nuclear power that seeks to deny its sovereignty offers vital lessons. For Ukraine, access to Taiwanese investments and technologies—including integrated circuits and electronic systems—means reduced dependence on Chinese components, which complicate its diplomatic efforts.

Ukraine offering its expertise in drone warfare to Japan and Taiwan in exchange for industrial investment—this is a remarkable geopolitical turnaround for a country that was receiving humanitarian aid just four years ago. Sybiha’s “drone diplomacy” is not merely a commercial strategy: it is a rebuilding of Ukrainian sovereignty through mutually beneficial partnerships. It deserves to be called what it is.

Seven Nations, an Unequivocal Declaration

The statement released following the Gdańsk summit on June 25, 2026—signed by seven nations, including several NATO members on the eastern flank—describes Russia’s hybrid campaigns as “persistent, coordinated, and escalatory” and calls for verifiable responses: additional sanctions, public exposure of Russian actors involved in hybrid operations, and accelerated attribution mechanisms. This declaration preceded Tsahkna’s remarks on drones by four days and follows the same logic: to name Russia’s actions, attribute responsibility for them, and refuse to allow the management of secondary incidents (drones in allied territory) to derail the main strategy (supporting Ukraine against a documented aggression).

The Gdańsk statement explicitly identifies Russia as the actor responsible for hybrid campaigns—including drone incidents. This preemptive attribution is strategically important: it prevents Moscow from successfully turning drone incidents into rhetorical ammunition against Ukraine. While seven NATO nations have officially declared that Russia is responsible for hybrid disruptions in their airspace and territory, Ukrainian drone incidents are documented within this framework—not as a Ukrainian threat, but as a consequence of Russian aggression.

The Ankara Summit on July 7–8: The Doctrine Will Be Put to the Test

The NATO summit in Ankara on July 7–8, 2026, will be the first major test of the Tsahkna doctrine’s coherence at the alliance level. Several concrete questions will be at stake: How does NATO officially respond to Ukrainian drone incidents on allied territory? What additional commitments will be made to strengthen Ukraine’s air defense and reduce the frequency of these incidents? Will the language regarding Russian responsibility for hybrid campaigns be at least as direct as that in the Gdańsk declaration? These questions are not technical—they are political, and their answers will determine whether Tsahkna’s position remains an Estonian national stance or becomes an alliance-wide doctrine.

According to RBC-Ukraine, the 2027 Ankara summit is already facing growing uncertainties—a sign that internal disagreements within the alliance over the pace and nature of support for Ukraine will not be resolved at a single summit. Ankara 2026 will serve as a benchmark: if its final texts are weaker than the Gdańsk declaration, it means that Russian diplomatic pressure has succeeded in dividing the alliance. If its texts are at least as direct, it means that the Tsahkna doctrine has won the consensus of all 32 members.

Gdańsk spoke the truth on June 25. Ankara must confirm that truth on July 7. Twelve days separate these two documents. In those twelve days, Putin has leveled accusations of a NATO conspiracy, Russia has continued to shoot down Ukrainian drones, and Tsahkna has said the price is acceptable. These are the conditions under which NATO is drafting its summit document. The outcome will reveal whether the alliance has the capacity to shape reality or whether it prefers to manage it diplomatically.

The “drone wall”: From Metaphor to Infrastructure

Faced with a surge in drone incidents on allied territory—including Ukrainian drones that have been diverted, as well as Russian drones violating the airspace of Sweden, Norway, Finland, Poland, Germany, and France—European leaders have agreed to develop a “drone wall” along their eastern borders. This project, announced in response to the Baltic incidents of May–June 2026, aims to create continuous radar coverage and interception capabilities along the NATO–Russia and NATO–Belarus borders.

Estonia activated its first border drone detection sensors on May 30, 2026. A U.S. anti-drone system has been deployed on NATO’s eastern flank. Latvian Commander General Kaspars Pudāns warned that Russia could exploit its drone advantage to attack the Baltic states by the end of 2028—an assessment that reflects how seriously the countries on the eastern flank perceive the threat. This drone barrier is not a response to Ukrainian drones—it is a defense infrastructure against the Russian threat that has the secondary effect of better mapping and monitoring all drones crossing the border.

Ukraine-Latvia Cooperation: A Model for Exchange

On June 13, 2026, Ukraine and Latvia signed an unprecedented exchange agreement: Ukraine will supply Latvia with attack drones, ground-based robotic systems, and maritime drone systems; Latvia will supply Ukraine with Latvian-made anti-drone systems. This bilateral exchange between two nations—one at war, the other on its immediate flank—illustrates the transformation of the defense market in the Baltic region. Latvia committed 10 million euros to joint defense manufacturing in 2025 alone.

This model of exchange—Ukrainian technology in exchange for allied resources—forms the backbone of Ukraine’s drone diplomacy in all directions: with the Netherlands (production hosting), Germany (STRILA orders), the EU (3.9 billion for drone purchases), Japan (Terra A1 co-development), and Latvia (bilateral exchange). The war has transformed Ukraine into the hub of a defensive cooperation network whose branches extend from Tallinn to Tokyo.

A Ukraine-Latvia agreement: attack drones versus anti-drone systems. This is arms diplomacy between two countries whose fates are linked by geography and a common threat. This isn’t aid—it’s an exchange. This shift in terminology is not superficial: it says something about the evolution of Ukraine’s status within the European defense ecosystem.

The Estonian Model of Contribution: A Small Nation, Maximum Commitment

Estonia is a country of 1.3 million people. Its GDP is modest compared to major European economies. And yet, in 2026, it is allocating at least 0.25% of its GDP—or approximately 110 million euros—to support Ukraine, with a primary focus on drones and anti-drone systems. Since the start of the full-scale invasion, it has provided Ukraine with military aid worth more than 1% of its GDP—a proportion that only a few NATO countries can match. The Cyber Coalition co-led by Estonia has raised over 1.4 billion euros for Ukrainian drone programs.

In 2026, Estonia also reallocated 500 million euros from its defense budget—by cutting back on certain traditional weapons programs—toward air defense, UAVs, and long-range strike capabilities. This strategic choice is consistent with the Tsahkna doctrine: in modern warfare, drones and air defense are more decisive than tanks and heavy artillery. Estonia has learned the lessons of the Ukrainian front and has restructured its own defense posture accordingly.

Estonian Intelligence: The Leading Authority on Russia

The Estonian Foreign Intelligence Service (VSSE) publishes an annual assessment of the Russian threat that is considered one of the most accurate and reliable among allied intelligence services. This analytical reputation lends Tsahkna particular credibility when he speaks about Putin’s state of mind or the economic impact of Ukrainian strikes. The head of Estonian foreign intelligence, Kaupo Rosin, has stated that time is no longer on Putin’s side and that within a few months, the Kremlin could lose the ability to dictate its terms. This assessment—published prior to Tsahkna’s June 29 statements—is the analytical foundation upon which his public position rests.

When Tsahkna says that the tone surrounding Putin “is no longer as optimistic,” he is speaking from an analytical context that few of his European counterparts can replicate. Estonia has been gathering intelligence on Russia for decades, has human sources within the Russian-speaking diaspora, and benefits from a geographical proximity that facilitates signals intelligence. This is not an opinion—it is a data-driven assessment that Estonia shares with its NATO allies in the appropriate forums.

Estonia’s VSSE is one of the most respected intelligence services on Russia within the entire alliance. When Tsahkna speaks of Putin’s morale, he is not speculating—he is assessing. This distinction is fundamental at a time when many European capitals are managing their relations with Moscow based on their own projections of what Putin wants. Estonia, on the other hand, analyzes what he is actually doing.

The “Fast Tracking European Investment in Ukraine’s Defense Act”

On June 29, 2026—the same date as Tsahkna’s statement—U.S. Senators Tim Kaine (Democrat, Virginia) and John Cornyn (Republican, Texas) introduced a bipartisan bill titled the “Fast Tracking European Investment in Ukraine’s Defense Act.” This bill aims to amend the U.S. Arms Export Control Act (AECA) to create a pre-approval mechanism allowing NATO countries and other partners to purchase and transfer certain types of ammunition to Ukraine through December 31, 2030, with the possibility of an extension through 2035.

The munitions in question are specifically identified: 155-mm artillery shells, long-range Excalibur shells, and ammunition for HIMARS and GMLRS systems. Senator Kaine explained the rationale as follows: “Our pragmatic legislation would reduce red tape to expedite the process allowing our allies to purchase and transfer certain munitions to Ukraine.” Senator Cornyn added: “The Ukrainians have demonstrated incredible resilience and adaptability on the battlefield, and I am proud that since the start of the war, the United States, NATO, and our other partners have come together to support Ukraine’s defense.”

The Bipartisan Significance: A Strong Political Signal

The bipartisan nature of this bill—sponsored by a leading Democrat and a leading Republican—is in itself an important political signal in the context of the Trump administration. It indicates that a cross-party coalition in the U.S. Senate supports expediting the mechanism for transferring ammunition to Ukraine via European allies, potentially bypassing some of the bureaucratic delays that have slowed previous deliveries. This bill does not guarantee its passage—but it documents the existence of bipartisan Senate support for increased military aid to Ukraine at a time when Ukraine’s deep-strike operations are proving their cost-effectiveness.

This U.S. legislative context completes the picture of Ukrainian drone diplomacy: while Sybiha is in Asia, Tsahkna declares the discomfort acceptable, Gdańsk assigns responsibility to Russia, and Latvia and Ukraine exchange drone systems—U.S. senators are working to expedite ammunition transfer mechanisms. These parallel developments in different capitals, on different fronts, converge toward the same goal: strengthening Ukraine’s resilience at a time when deep-strike operations are proving their effectiveness.

Kaine and Cornyn—a Democrat and a Republican. This bipartisan duo in the U.S. Senate conveys something that summit speeches cannot express as clearly: support for Ukraine transcends partisan lines when military results are tangible. The economic effectiveness of deep-strike operations, documented by Tsahkna through his intelligence sources, is building its own legislative consensus.

Seoul: Between Pragmatism and Russian History

Sybiha’s visit to Seoul illustrates the complexity of Ukrainian diplomacy in East Asia. South Korea has supported Ukraine diplomatically and provided repeated humanitarian aid. But its relations with Russia—historically viewed as a potential mediator with North Korea—complicate direct military engagements. New President Lee Jae Myung has declared a “pragmatic” foreign policy—a term that, in the context of the war in Ukraine, can mean different things depending on the circumstances.

The factor that further complicates the relationship is embedded in the conflict itself: North Korean soldiers are fighting alongside Russian forces in Ukraine, and some are being held by Ukrainian forces. These detainees are legally South Korean citizens under Seoul’s constitutional law. This unique reality—South Korea, whose legal citizens are fighting against an informal ally—is one of the topics Sybiha certainly had on his agenda for Seoul. Russia has provided North Korea with experience in modern warfare—and North Korea has provided Russia with ammunition and troops. This closed loop directly affects South Korea’s security.

Japan: The Most Advanced Relationship

Among its Asian partners, Japan is the one whose relationship with Ukraine has evolved the most. Defense expert Masayuki Masuda, director of Chinese studies at Japan’s National Institute for Defense Studies, put it this way in an interview: “When comparing the relative strengths of Russia and Ukraine at the start of the war, it’s clear that Ukraine has performed very well, and much of that is due to drones.” Japan explicitly recognizes Ukrainian drones as a model to learn from and adapt for its own island defense—an archipelago vulnerable to the same types of asymmetric threats that Ukraine has developed the tools to counter.

Japan’s contribution to the PURL program in May 2026, the deployment of Japanese military personnel to NATO headquarters in Wiesbaden, Prime Minister Sanae Takaichi’s confirmation of continued support at the latest G7 summit, and the development of the Terra A1 drone in partnership with Amazing Drones—these elements paint a picture of a rapidly evolving strategic partnership, constrained by Japanese legal limitations but advancing in every available arena.

Japan is developing an interceptor drone with a Ukrainian startup and sending it to Ukraine for testing in April 2026—this is defensive cooperation between two countries that geography has little reason to bring together, but which a common threat (Russia, China, and North Korea) has united. This convergence of threats is the real driving force behind Ukrainian drone diplomacy in Asia. Sybiha doesn’t need to sell much: the threat sells itself.

What the Doctrine Does Not Resolve

Tsahkna’s position—accepting drone incidents as the price of destroying the Russian economy—has solid strategic coherence. It also has real limitations. It works when Ukrainian drones that stray into allied territory do not cause civilian casualties. It works when such incidents remain relatively rare and manageable. It works when other NATO countries share Estonia’s assessment of the benefits of the Ukrainian strike campaign. None of these conditions is guaranteed in the long term.

Latvian General Pudāns has warned that Russia could exploit its drone advantage to attack the Baltic states by the end of 2028. If drone incidents—whether Ukrainian or Russian—were to cause civilian casualties on allied territory, the political pressure to restrict Ukrainian operations would become very difficult to ignore. The Tsahkna doctrine is a doctrine for managing acceptable risk under current conditions—it is not a doctrine that is invulnerable to all future conditions.

The Structural Response: Improving Ukraine’s Control Over Drone Trajectories

The long-term response to drone incidents is not to indefinitely accept the unacceptable—it is to improve the systems that allow Ukraine to more precisely control the flight paths of its drones in areas contested by Russian electronic warfare. The expansion of Ukraine-Estonia cooperation on drones on June 3, 2026; the Estonian border detection sensors activated on May 30; and the mission by Ukrainian experts to the Baltic states proposed in May 2026—all these initiatives work toward the same goal: reducing the frequency of incidents without diminishing the effectiveness of the strike campaign.

The technological solution to the problem is more challenging than the political statement. Russian electronic warfare, which diverts Ukrainian drones, operates in real time within a contested electromagnetic environment, with capabilities that are continuously improving. The Ukrainian response—GPS-free navigation, inertial guidance systems, and autonomous guidance terminals—is making progress, but not fast enough to completely eliminate incidents. In the meantime, the Tsahkna doctrine remains the most honest political response available: identify the problem, assign responsibility to the right party, and refuse to let secondary incidents derail the main strategy.

The Tsahkna doctrine says: the cost is acceptable. The technological response says: let’s work toward no longer having to pay that cost. These two positions are not contradictory—they are complementary. One manages the present with honesty. The other builds a future where the problem no longer arises. This is mature strategy in an environment of real uncertainty.

A June 2026 agreement that redefines defense relations

The agreement signed in June 2026 between Ukraine and Latvia—Ukrainian attack drones and robotic systems in exchange for Latvian anti-drone systems—is the first documented bilateral agreement for the symmetrical exchange of drone systems between Ukraine and a NATO ally. Its structure reflects the transformation of Ukraine’s status within the European defense ecosystem: no longer merely a recipient of aid, but an active contributor of capabilities that its allies do not possess on the same scale or with the same level of operational experience.

Latvia will receive Ukrainian attack drones that will enable it to develop longer-range strike capabilities. Ukraine will receive Latvian anti-drone systems that will help defend against the continuous waves of Russian Shaheds. The financial terms and quantities have not been publicly disclosed—but the structure of the agreement speaks volumes: two countries on NATO’s eastern flank have decided that they each have something to offer the other, and that a direct exchange is more effective than going through the alliance’s centralized mechanisms.

A Model That Can Be Replicated

The Ukraine-Latvia agreement could serve as a model for a series of similar bilateral agreements: Ukraine-Estonia, Ukraine-Poland, Ukraine-Finland, and Ukraine-Netherlands. Each NATO country is developing specific capabilities that Ukraine may wish to acquire, and in exchange, Ukraine offers unique operational experience in drone warfare that these same countries are seeking to integrate into their own doctrines. This shift toward bilateral defense cooperation complements NATO’s central mechanisms—it does not replace them, but it allows for a speed and specificity that alliance-level processes cannot always provide.

This bilateral dynamic is all the more important in a context where multilateral mechanisms are subject to political pressures: the need for consensus, dynamics with the Trump administration, and divergent positions on the timeline for Ukraine’s NATO membership. Bilateral agreements are not subject to these constraints—they reflect the willingness of two sovereign governments to cooperate in their mutual interest. It is precisely this model that Sybiha’s “drone diplomacy” seeks to replicate, from Riga to Tokyo.

Ukraine-Latvia: drones for drones. Ukraine-Japan: expertise for investment. Ukraine-Netherlands: outsourced production for capacity guarantees. These bilateral agreements weave a network of mutual dependencies that is, in the long run, more robust than a summit declaration. Ukraine is building its own safety net, country by country, agreement by agreement. This is long-term diplomacy—slow but irreversible.

The IT Coalition: A Unique Support Architecture

The IT Coalition, co-led by Estonia—with Ukraine as its primary beneficiary—has raised more than 1.4 billion euros for the development of military communications systems, digital infrastructure, and battlefield management technologies. In 2026, Estonia will contribute an additional 5.7 million euros toward the digital components of Ukraine’s defense architecture. This coalition—which brings together dozens of donor countries under a flexible framework that avoids the bureaucratic constraints of formal NATO structures—is an example of the Eastern Flank’s ability to build rapid and effective support mechanisms when the political will is present.

The €1.4 billion in funding for Ukrainian defense technologies is strategically linked to drone diplomacy: secure communications systems, drone management platforms, and digital command infrastructure—all of which constitute the technological backbone without which even the most advanced drones are useless. Estonia has realized that support for Ukraine cannot be limited to weapons systems—it must include the technological architecture that makes them function. This is precisely what this coalition is funding, and it is what Sybiha’s “drone diplomacy” seeks to replicate in new regions.

Estonia’s Cybersecurity Expertise as a Unique Asset

Estonia is known worldwide for its expertise in cybersecurity and digital governance—it suffered the first documented state-sponsored cyberattack in 2007 (by Russia) and has since built one of the world’s most advanced digital resilience architectures. This expertise is directly applicable to drone warfare: jamming-resistant autonomous drone navigation, secure command-and-control systems, and large-scale drone fleet management platforms—all of these systems rest on a solid cybersecurity foundation. By co-leading the IT Coalition, Estonia is transferring some of this expertise to Ukraine.

This transfer of cyber expertise is all the more valuable given that Russian electronic warfare—which is responsible for diverting drones into allied territory—is fundamentally a problem of cyber operations applied to navigation. Improving the resilience of Ukrainian drones against Russian jamming requires exactly the kind of expertise that Estonia has been developing since 2007. It is no coincidence that the expansion of Ukraine-Estonia cooperation on drones took place on June 3, 2026, the day after the first Ukrainian drone was shot down over Estonian territory: the incident created a cooperative emergency that the two countries turned into an opportunity for strengthening their partnership.

Estonia was the victim of the first state-sponsored cyberattack in 2007. Today, it co-leads a 1.4-billion-euro coalition for Ukrainian defense technologies. This journey—from victim to leader—is the most valuable lesson Estonia can offer Ukraine: invest in technological expertise after every attack until you become the country others come to learn from. Ukraine is on that path.

The Ukrainian Paradox: Chinese Components in Ukrainian Drones

Ukraine’s drone diplomacy in Asia is complicated by a well-documented industrial reality: Ukrainian drones contain electronic components, some of which come from China. This dependence—shared by many countries and industries in the drone sector—creates tension in discussions with Taiwan and an asymmetry in relations with Beijing: Ukraine officially recognizes the PRC, is partially dependent on its components for its defense industry, and simultaneously seeks to develop partnerships with actors that Beijing considers part of its sphere of influence. This equation is difficult to resolve in the short term.

The RBC-Ukraine analysis notes that Nataliya Butyrska of the New Europe Center stated: “China is a country that some in Ukraine still call a strategic partner.” This phrasing—“some in Ukraine,” a subtle distancing—reflects the internal Ukrainian debate over how to manage the relationship with Beijing. On one hand, there is the reality of industrial dependence. On the other, there is the recognition that China indirectly supports Russia’s war effort by supplying dual-use technologies and maintaining trade that partially offsets Western sanctions.

Reducing Dependence as a Strategic Goal

Sybiha’s drone diplomacy in Asia can be interpreted, among other things, as a strategy to reduce dependence on Chinese components: by developing industrial partnerships with Japan and Taiwan—whose companies produce advanced electronic components—Ukraine seeks to diversify its supply chains to reduce exposure to the political and economic risks associated with its dependence on Beijing. This is not a short-term goal—substituting components in the defense industry takes years. But it is a coherent strategic objective, of which Sybiha’s Asian diplomacy is a concrete manifestation.

Taiwanese defense companies have already opened subsidiaries in Eastern Europe to work with Ukrainian manufacturers—a first step toward a component supply chain that bypasses dependence on Beijing. The agreement with Japan’s Terra Drone for the co-development of the Terra A1 is another example of this diversification. These partnerships are not yet sufficiently developed to radically change Ukraine’s industrial landscape—but their direction is clear, and accelerating them is one of the implicit goals of Sybiha’s tour.

Ukraine uses Chinese components to manufacture drones that are destroying an army that China indirectly supports. This industrial paradox is not unique to Ukraine—it reflects the state of global electronics supply chains. But for Ukrainian diplomacy in Asia, it creates a real constraint that Sybiha must navigate carefully. Supplier diversification is not just an industrial strategy—it is applied geopolitics.

The Limits of a Nation’s Stance Within an Alliance

Tsahkna’s analytical and doctrinal clarity has structural limitations within the framework of a 32-member alliance. Estonia may accept that Ukrainian drones fall on its territory. It cannot decide on behalf of Hungary, Slovakia, or any other member that perceives the situation differently. Nor can it determine NATO’s rules of engagement regarding Ukrainian drones entering allied airspace—these rules are decided collectively. The Tsahkna doctrine is a national contribution to an alliance-wide debate that remains open.

This debate will be decisive at the Ankara summit. If NATO adopts a common position that follows Tsahkna’s logic—attributing responsibility for the incidents to Russian electronic warfare and refusing to allow these incidents to undermine support for Ukraine—then the Estonian national doctrine will have become alliance doctrine. If NATO produces an ambiguous text that does not clearly assign responsibility and that implies restrictions on Ukrainian operations, Tsahkna’s position will remain a courageous exception within a consensus that has isolated it.

Russia Watching Ankara

The Ankara summit is taking place against a backdrop in which Putin has just publicly accused NATO and Ukraine of “plotting attacks” against Russia—an accusation dismissed as propaganda by the allies, but one that is specifically aimed at putting pressure on those alliance members most susceptible to rhetoric of escalation. If Ankara produces a statement that incorporates, even implicitly, the Russian narrative of “NATO as a provocateur,” Putin will have succeeded in using his rhetorical accusation to influence the summit communiqué of a 32-member alliance. This would be an unprecedented Russian diplomatic victory in this conflict.

The response to this rhetorical pressure lies precisely in the Tsahkna doctrine: to call drone incidents what they are (the consequence of Russian electronic warfare), to assign responsibility to the correct party, and to refuse to let secondary incidents derail the main strategy. If Ankara adopts this framework—and if its statements are as direct as the Gdańsk declaration—then the Tsahkna doctrine will have passed its most important alliance test since its formulation on June 29, 2026.

Putin views Ankara through the eyes of a strategist who has realized that rhetoric can replace missiles when missiles are no longer enough to advance. The question is whether NATO has grasped the same concept in reverse: that rhetorical clarity—direct, assigning responsibility, rejecting ambiguity—is itself a weapon in this conflict. Tsahkna has understood this. Do the other 31 members understand it as well?

June 29, 2026, as a Turning Point

June 29, 2026, brings together several simultaneous signals that, taken together, outline an emerging doctrine. Tsahkna declares that a certain level of discomfort is acceptable. Sybiha leaves for Asia with proposals for drone cooperation. Kaine and Cornyn introduce their bipartisan bill to accelerate deliveries. The June 25 Gdańsk Declaration attributes responsibility for hybrid campaigns to Russia. These converging developments are not the result of central coordination—they stem from a shared assessment: Ukraine’s deep strikes are effective, their cost-effectiveness is well-documented, and no secondary diplomatic discomfort should justify curtailing them.

This assessment—articulated in Tallinn but shared from Washington to Tokyo—is the doctrinal foundation upon which the Ankara summit must take a stance. If NATO confirms this assessment and incorporates it into its official documents, the Tsahkna doctrine will have become alliance doctrine. If the summit produces a weaker consensus, Estonia will remain a courageous yet isolated voice in a debate that the alliance refuses to resolve. This outcome—courageous yet isolated—is not unprecedented in NATO’s history. Nor is it without consequences for the alliance’s cohesion.

Ukraine as an Exporter of Doctrine: The Ongoing Shift

June 29, 2026: Tsahkna in the Financial Times, Sybiha at the airport bound for Asia, Kaine and Cornyn in the Senate. These three simultaneous developments in three different capitals share a common assessment: Ukraine’s campaign of deep strikes is working, the diplomatic discomfort it causes is manageable, and holding Ukraine back to avoid this discomfort would serve Russian objectives. This convergence is not coordinated—it is driven by the same facts. It is a convergence that deserves to be acknowledged.

Beyond drone incidents and diplomatic statements, the investigation I have just conducted reveals a deeper shift: Ukraine is becoming an exporter of contemporary military doctrine. This is not a metaphor—it is a reality enshrined in agreements with Latvia, Japan, the Netherlands, and Germany. The Cyber Coalition co-led by Estonia, with 1.4 billion euros invested, is its most institutionalized manifestation. Sybiha’s Asian tour is its most recent diplomatic expression.

This shift—from a Ukraine begging for weapons to a Ukraine negotiating technological partnerships on equal terms—is not guaranteed. It depends on continued Western military support, Ukraine’s industrial capacity to maintain its production rates, and the alliance’s resolve not to yield to Russian rhetorical pressure. But the momentum is underway, it is well-documented, and it is irreversible at its deepest foundations: Ukraine has proven something that contemporary military doctrine manuals can no longer ignore.
