At the recent SAHA Expo 2026, Turkey unveiled a mock-up of the Yildirimhan (Thunderbolt) and released details about the long-range, four-engined, liquid-fueled ballistic missile. The designation “Yildirimhan” refers to Ottoman Sultan Bayezid I, known as “the Thunderbolt,” circa 1400 AD. He was known for acting faster than his enemies, striking before alliances formed, and crushing resistance with swift effectiveness. The naming approach sends a geopolitical message as loud as the missile itself.

Turkey’s pursuit of an advanced long-range missile capability reflects a broader shift in its strategic ambitions, regional influence, and state security priorities. Once seen as sufficient to defend NATO’s southeastern flank but not fit for EU membership, Turkey has increasingly sought to redefine itself as an independent geopolitical power. No longer willing to be merely a buffer state for Western interests, Ankara is actively transforming into an independent, assertive geopolitical power capable of shaping the Middle East, the Eastern Mediterranean, the Black Sea, the Caucasus, Central Asia, and even Europe itself.

A key part of this transformation has been Turkey’s increasing focus on defense self-sufficiency, domestic military technology, and strategic autonomy. Within this context, Turkey’s declared goal to develop long-range ballistic capabilities, including at Intercontinental Ballistic Missile (ICBM) levels, demands America’s full attention.

We may be witnessing the ultimate manifestation of a state seeking to decouple its sovereign interests in security and power projection from historical external arms dependence and traditional “alliance reliance” Western security guarantees.

Turkey’s missile ambitions are likely part of a broader effort to reduce its dependence on foreign defense suppliers that either restrict access to advanced weapons capabilities or sell suboptimal weapons systems that are difficult to integrate, costly to maintain, or are just ineffective. Turkish leaders have frequently expressed frustration with arms embargoes, sanctions, and restrictions imposed by allies during political disputes. These tensions have accelerated Turkey’s investment in domestic aerospace, drone, missile, and satellite-launch industries, framing these programs as symbols of national sovereignty, technological progress, and strategic independence.

Concurrently, Turkey’s increasingly unstable security situation has incentivized its need for long-range deterrent capabilities. Ankara is not only positioned at the crossroads of Europe and Asia, but it is also close to several regional flashpoints involving Ukraine, Russia, Iran, Iraq, Syria, and ongoing tensions in the Eastern Mediterranean. Turkey desires increased geopolitical influence and greater operational freedom. Developing long-range missile systems, therefore, has both military and political importance, boosting deterrence and signaling Turkey’s rise as a regional power capable of independent strategic action. In short, Turkey intends to shape these challenges moving forward, and more autonomy is the price of leadership.

Turkey’s long-range missile development, fueled by its National Technology Initiative, is part of a larger investment in civilian space and satellite launch initiatives, which were officially presented as peaceful technological advancements designed to strengthen communications, scientific research, and national prestige. Turkey’s commitment to this effort is now on display in Somalia, of all places, where it is constructing a spaceport to support future launch operations. The technologies required for satellite launch vehicles closely overlap with those needed for ballistic missile systems, including multi-stage rocket propulsion, precision guidance, and reentry vehicle engineering. As a result, advances in Turkey’s space program will expedite its long-range ballistic missile development.

Although Turkey does not possess nuclear weapons and is a signatory to the nuclear non-proliferation treaty, occasional statements by Turkish officials criticizing the global nuclear order have fueled international speculation that Turkey might seek its own nuclear arsenal in the future. Any ICBM capable of carrying a 6,000-pound weapons payload over approximately 6,000 kilometers would have limited strategic value as a conventional weapon, but with a nuclear warhead, it would dramatically alter the strategic calculations across the region and beyond.

The possibility of a reduced American nuclear commitment to NATO Europe could increase Turkey’s importance in the same way. If European governments keep pushing Washington out of NATO, the result will be that Europe must pay for and develop its own nuclear capabilities—another form of deterrence. France has introduced its new doctrine of “forward deterrence,” which advocates for an expanded nuclear arsenal and a broader nuclear deterrence umbrella over all of Europe, but only under French operational control. Both Poland and Germany have conveyed interest in alternative nuclear arsenals to bolster European deterrence. In this context, Turkey could see its long-range missile capabilities as an opportunity to fill the deterrence gap identified by other NATO leaders and as a pathway toward future nuclear delivery capability if political circumstances change.

At the same time, Turkey’s pursuit of advanced missile systems could generate tensions within NATO if those capabilities are not carefully integrated into the alliance’s broader strategic framework. Some European allies may view Turkish missile development—and any potential future nuclear ambitions—as destabilizing, given Ankara’s sometimes contentious relationships with other NATO members. Such developments would inevitably raise questions regarding missile security, command-and-control arrangements, escalation risks, and about whether Turkey’s long-term strategic objectives remain fully aligned with broader alliance priorities.

Whether Turkey ultimately seeks to develop an arsenal of nuclear-armed ICBMs remains uncertain. What is clear, however, is that Turkey’s long-range missile ambitions are real and appear to support both a broader long-term strategy of autonomous power projection and a more immediate effort to expand capabilities that could contribute to NATO’s evolving long-range strike and nuclear deterrence requirements.

Turkey’s growing missile capabilities reflect a clear strategic goal: to make itself an independent, technologically advanced, and influential military power in an increasingly unstable region; thereby, demonstrating that Turkey is not only a force to be reckoned with but also a partner to be allied with. Its growing missile ambitions reflect a strategic objective of establishing Turkey as an independent, technologically advanced, and regionally influential military power capable of operating with greater strategic autonomy in an increasingly unstable security environment. Turkey should not be viewed merely as a state to be reckoned with, but as an indispensable ally and arms supplier.

Turkey’s ICBM: Ambition for Autonomy was originally published on Global Security Review.

That contradiction has come into sharp relief during the presidency of Donald Trump, whose blunt interest in Greenland exposed what European diplomacy had long obscured. The controversy was framed as eccentricity or provocation, but the underlying grievance was familiar. For decades, the United States has underwritten European security while European governments reduced their defense investments in favor of generous welfare systems and subsidized industry, confident that the American half of the alliance would absorb the risk. The Greenland crisis has simply made that imbalance visible.

Greenland’s Strategic Reality

Greenland occupies a unique strategic position. It sits in the western hemisphere astride the Arctic approaches to the “GIUK Gap,” hosting critical space and missile-warning infrastructure essential to NATO’s early-warning architecture. The 2004 Defense Greenland Agreement between the United States and Denmark, Amending and Supplementing the Agreement of April 27, 1951, explicitly limits the US defense area in Greenland to Thule (Pituffik) Air (Space) Base only.

With Arctic sea lanes opening and undersea infrastructure becoming a focal point of competition, Greenland’s strategic importance is no longer peripheral but central. The question now confronting Europe is whether the small Kingdom of Denmark and, by extension, Europe, can demonstrate even minimal sovereignty over a territory it insists is non-negotiable but has left undefended for some 250 years.

Article 3 of the NATO Treaty states: “In order more effectively to achieve the objectives of this Treaty, the Parties, separately and jointly, by means of continuous and effective self-help and mutual aid, will maintain and develop their individual and collective capacity to resist armed attack.” Put plainly, Denmark is obligated to maintain—on its own and on a continuous basis—the capacity to defend all its territory. By that standard, Denmark has failed to meet its Article 3 responsibilities for a very long time, if it ever has.

Despite its strategic importance, Greenland remains vulnerable and economically neglected. This is not an accident or a bureaucratic oversight. It is the result of a long-standing assumption—that the United States would indefinitely guarantee European sovereignty and sustain its social-economic model. That assumption no longer holds. Strategic competition is shifting away from open confrontation toward constant pressure, probing actions, and fait accompli. In this world, sovereignty is not something you can merely declare. It is something you must demonstrate.

Trump, Europe, and the Sovereignty Question

Trump’s narrative about Greenland was widely dismissed as transactional or unserious. Stripped of tone, however, the message was structural: As the Arctic presents opportunity, Greenland is even more strategically vital to North American security than ever before, and someone must take responsibility for securing and developing it.

This tension among NATO allies reflects a broader post–Cold War pattern. Europe expanded its regulatory, economic, and political influence while allowing NATO military funding and capability to atrophy. The resulting system elevated process, norms, and legalism over hard power security, sovereignty, and deterrence.

The renewed United States demand for Greenland exposes the limits of that model. If Denmark cannot even mount a minimal defense of its own territory, the problem is not American overreach, but European credibility.

The UK Corollary

In a striking act of geopolitical idealism, the United Kingdom has agreed to cede sovereignty over Diego Garcia to Mauritius—an “own goal” that harms US interests. Long regarded as an “unsinkable aircraft carrier,” Diego Garcia has been a cornerstone of US and UK power projection across the Middle East, East Africa, South Asia, and beyond for decades.

After years of legal and diplomatic pressure—culminating in adverse rulings from international courts and the United Nations—the UK concluded that continued unilateral control of the Chagos Archipelago was politically unsustainable in this rules-based international order. In 2024, London agreed to transfer sovereignty to Mauritius, a state increasingly influenced by Beijing, while attempting to preserve military access through a long-term, UK-funded lease.

On paper, operations continue. Leverage shifts from occupant to owner. Sovereignty matters: once surrendered, access rests on political permission rather than power. A future Beijing-aligned Mauritius could abrogate agreements or revoke leases, leaving the US and UK strategically stranded, “out of runway” and out of business in the Indian Ocean.

Like Diego Garcia, Greenland’s strategic value lies in assured access. Trusting that allies will always act in America’s best interest is folly. Access without ownership is always conditional; sovereignty without power is fragile. Both cases reveal the same risk—vital territory left exposed at a moment when great-power competition demands clarity, presence, and resolve.

Sovereignty Requires Adequate Organic Defense

Defending Greenland does not require national militarization on Cold War terms. It does not require large permanent formations or aggressive posturing. But it does require capability, presence, and integration of real forces tied to real geography. The fantasy of the [European] Liberal [global] Rules-based order is no longer sufficient alone.

A credible defense posture requires permanent ground, air, and naval forces. Presence must be sufficient to assert territorial control, secure the Arctic approaches, and protect key infrastructure. Additionally, it requires fifth-generation airpower, supported by NATO enablers sufficient to project air sovereignty and assert control over the airspace of the GIUK, along with integrated maritime and subsurface awareness to control approaches, advanced air and missile defense for critical nodes, and the logistics infrastructure required to sustain operations in an Arctic environment.

This is not an escalation; it is the minimum viable defense posture for the territory Denmark claims sovereignty over, NATO depends upon, and the Western Hemisphere demands. Anything less than that is not restraint; it is abdication.

What Denmark Can Do

For Denmark to retain its kingdom, it must fervently acknowledge that China and Russia are expanding their Arctic ambitions and that continuing to ignore or neglect this threat risks losing Greenland to another great power’s orbit. Denmark does not need to defend Greenland alone, but it must lead and meet its Article 3 responsibilities. Sovereignty cannot be subcontracted. First, Denmark must accept that a visible, persistent presence is non-negotiable. A battalion-sized force and a fighter squadron on Greenlandic soil are not a burden; they are a declaration of responsibility.

Second, Denmark must align force posture with geography. Arctic defense is not a side mission; it is central to Denmark’s strategic responsibilities and credibility. That requires prioritizing basing, sustainment, and readiness over symbolic deployments there or elsewhere.

Third, Denmark must integrate defense with economic development. Resource extraction, energy production, and infrastructure are not separate from security; they are its foundation. Without an economic base, defense remains episodic and less affordable. For the collective West, energy and critical element security is national security. If Denmark cannot execute these steps—even with allied support—then sovereignty is no longer exercised; it is merely asserted.

How Europe Can Contribute Without Posturing

Greenland offers Europe an opportunity to demonstrate what regional shared deterrence looks like. Contributions need not be equal in scale, but they must be meaningful in effect. Rotational air defense units, maritime patrol aircraft, icebreaking capacity, logistics support, and infrastructure investment tied directly to defense requirements would materially strengthen deterrence without grandstanding.

This is where Europe’s economic power must finally align with its strategic claims. Shared deterrence is not about symbolism or declarations. It is about complementary capability and sustained commitment.

Can Europe Move Fast Enough?

The decisive variable is time. Ten-year roadmaps and aspirational targets are irrelevant. Greenland’s exposure is immediate. The longer Europe delays, the more it reinforces the perception that sovereignty exists only on paper. Delay only serves to validate President Trump’s strategic demand.

Credible deterrence must begin within weeks, not months or years. Initial deployments need not be perfect, but they cannot be symbolic political statements devoid of the credible military capacity required for the mission. They need to be visible, permanent, and expandable.

The Consequences of Failure

Failure in Greenland would reverberate far beyond the Arctic. If Denmark cannot defend Greenland with allied assistance, then European claims of strategic autonomy collapse and NATO’s credibility fractures geographically. The United States will either act unilaterally or disengage selectively. Resource development will proceed without European leverage. Most damaging of all, failure would confirm a lesson Europe can no longer afford: that idealism and process cannot substitute for balance-of-power realism, and that international norms cannot enforce themselves. Where previous US presidential administrations relied on alliances, basing agreements, and quiet influence, President Trump has framed the issue in transactional terms: if Greenland was strategically vital, someone had to take responsibility for securing and developing it.

Conclusion

Greenland is not a crisis invented in Washington. It is the result of allied neglect and free riding. Persistent underinvestment in defense, miscalculation of threats, and a readiness among many allies to subordinate their sovereignty to international norms have produced a growing crisis of confidence in the United States. This can only be reversed with real power projection and a NATO commitment to peace through strength.

Denmark does not need to match American power. It needs to demonstrate agency, urgency, and empathy. Denmark and greater NATO must listen to its most powerful ally and address its security concerns with great alacrity. Rather than escalating the rhetoric, Denmark should admit its negligence and mitigate the shortfall now. Europe does not need to replace the United States or drive it out of the alliance. It needs to stop pretending that sovereignty is cost-free or that it can be reliably substituted with treaties in perpetuity.

This President demands more of the alliance to defend America’s northern approaches. If Denmark and the rest of NATO cannot meet that demand, the United States will. What is being asked is reasonable. The Arctic is now NATO’s second front. If Europe cannot meet that demand here, it has become sovereignty insolvent and should stop speaking of autonomy elsewhere. Because in the end, reality does not respond to intention, only to real and persistent power.

Such an alliance is needed most in the Indo-Pacific region where China is attempting, with some success, to challenge the American-led rules-based international order. Growing American alliances and partnerships beyond current bilateral relationships is the solution.

A more tailored and comprehensive approach involving Australia, Japan, and South Korea should serve as the beginning of an alliance that could expand and counter Chinese efforts in more than just the military realm. Such an alliance could bolster American nuclear deterrence and assurance in the region and directly support regional stability. A need for increased security cooperation in the Indo-Pacific is a clear and obtainable objective.

Formalizing a Multilateral Treaty Organization

Creating a regional multilateral treaty-bound organization with Australia, Japan, and South Korea will institutionalize defense cooperation and bolster collective security. This organization could formally facilitate regular interoperability consultations, increase joint coalition exercises, and more effectively coordinate responses to regional threats. By formalizing these relationships, the US and its allies can ensure a cohesive and effective deterrence strategy with more eloquence throughout the Indo-Pacific.

Establishing a new treaty organization will be challenging, but the cost-benefit will be worthwhile in the long term. This formality directly supports the diplomatic leg of the diplomatic, information, military, and economic (DIME) model.

Equipping Allies with Nuclear-Capable F-35s

Expanding the sale of nuclear-capable F-35As to Australia, Japan, and South Korea represents a significant advancement in regional coverage of the US nuclear umbrella. These next-generation fighters provide a capable and credible nuclear capability to prepare allies for future conflict, allows increased power projection against potential adversaries, and bolsters the operational compatibility between American forces and allies.

By integrating these aircraft into their respective air forces, allies can contribute to a more dynamic and responsive deterrence posture if a need arises as the geopolitical environment changes. And, if the alliance expands as expected, F-35s can compensate for their range limitations by “island hopping” their way to the fight or allies can build their own aerial refueling capability.

The presence of highly mobile nuclear-capable platforms increases regional solidarity in a strategically tailored way that messages adversaries that aggression will not be tolerated. Given growing Chinese aggression, this is an important task.

Developing Supporting Infrastructure

To maximize the efficacy of these new capabilities, it is crucial to establish a robust infrastructure that supports the deployment and maintenance of nuclear-capable assets for

forward-based power projection. This includes upgrading the host nations’ airfields, maintenance facilities, and command-and-control systems.

Such infrastructure will allow seamless integration of allied forces into joint operations and ensure sustained operational readiness. The host nations will need to take charge of the economic development required to maintain the increase in capability and its continued sustainment in the long term—relieving some of the costs that would otherwise be borne by the American taxpayer.

Increasing SSBN Port Calls and Coalition Heavy Bomber Task Force Exercises

Boosting the frequency of American ballistic missile submarine (SSBN) port calls and conducting more coalition heavy bomber task force exercises will further strengthen the deterrence posture within the region. American SSBN presence provides a method to showcase a strategic, survivable deterrent, while heavy bombers enable power projection. Conducting joint operations further solidifies a multinational force’s allied resolve and compatibility.

Additionally, the United States could showcase the ability to provide a safe haven for the required heavy bomber task forces if the need arises. These activities would demonstrate an increase in enhancing regional security ties and reassuring allies of the continuation of American commitment. The United States could also sell the B1 and B2 bombers it plans to retire to its allies.

Conclusion

Strengthening American nuclear deterrence in the Indo-Pacific requires a multifaceted approach that continues to foster positive alliances and partnerships that advance capabilities. Honoring these commitments showcases allied resolve to hold adversaries at risk with well-calculated multilateral decision-making processes and regional cooperation. By equipping Australia, Japan, and South Korea with nuclear-capable F-35As, establishing the necessary infrastructure, formalizing multilateral agreements, and increasing strategic exercises with ballistic missile submarines and heavy bombers, the US and its allies can enhance deterrence.

These measures will solidify regional defense cooperation, amplify the efficacy of the nuclear umbrella, and ensure a regional multilateral response to potential nuclear threats, thereby reinforcing the American commitment to maintaining stability and countering China’s growing influence across the region.
