Executive Summary

The Munich Security Conference of February 2026 revealed profound fractures in the transatlantic alliance that carry significant implications for Singapore’s security architecture. As Europe confronts an unreliable America and a resurgent China, Singapore—a small city-state dependent on a rules-based international order—faces mounting strategic challenges that demand careful recalibration of its defense posture and diplomatic positioning.

The Greenland Shock: When Alliance Reliability Collapses

The most dramatic revelation at Munich was not what was said, but what remained unspoken. Secretary of State Marco Rubio’s speech conspicuously avoided addressing the elephant in the room: President Trump’s threats to seize Greenland from Denmark, a NATO ally since 1949. This omission spoke volumes about the deteriorating state of American alliance commitments.

For Singapore, the Greenland crisis represents a watershed moment. If the United States threatens military action against a founding NATO member over territorial ambitions, what does this signal about American reliability toward non-treaty partners in Asia? Singapore has cultivated what scholars describe as a “quasi-alliance” with the United States—deep defense cooperation without a formal mutual defense treaty. The city-state maintains the second-largest permanent foreign military presence in America through training detachments in Idaho, Arizona, and Texas. American aircraft carriers routinely dock at Singapore’s Changi Naval Base, designed specifically to accommodate them. The arrangement has been mutually beneficial for decades.

But the Greenland episode exposes a fundamental vulnerability in Singapore’s strategic calculus. When alliance commitments to treaty partners become negotiable, informal partnerships become exponentially more precarious. Trump’s statement that preserving NATO versus seizing Greenland “may be a choice” suggests a transactional worldview where long-term strategic partnerships can be discarded for short-term gains.

The Defense Technology Dilemma

Singapore’s military modernization strategy is deeply intertwined with American defense technology. The Republic of Singapore Air Force has committed to procuring 20 F-35 Lightning II fighter aircraft—12 F-35Bs and 8 F-35As—with the first deliveries scheduled for late 2026. This represents a multi-billion dollar investment in America’s most advanced fighter platform.

The F-35 procurement illustrates Singapore’s defense dependencies. These aircraft require regular software updates from the United States to remain fully operational. Given that Germany faces similar concerns about its 35 F-35s ordered to carry American B61 nuclear weapons, the question becomes acute: can Singapore rely on continuous American support for critical military systems when Washington’s commitment to its closest allies appears increasingly contingible?

Singapore’s defense inventory reveals the depth of this technological dependency. American-made HIMARS rocket launchers, which have proven decisive in Ukraine, form part of Singapore’s artillery arsenal. U.S. engines power Singapore-designed armored vehicles including the Bionix, Bronco, and Terrex. The relationship extends beyond hardware to operational doctrine—the Republic of Singapore Air Force is equipped and trained to integrate seamlessly into U.S.-led operations, mirroring American operational concepts.

The Munich conference’s implicit message—that Europe must develop strategic autonomy from American defense systems—resonates powerfully in Singapore. However, the European experience demonstrates the difficulty of this transition. Europe’s defense industry remains fragmented, and major collaborative projects like the Franco-German FCAS fighter program have stalled due to disagreements over industrial leadership. For a city-state with Singapore’s limited domestic market and industrial base, developing indigenous alternatives to American defense technology presents even steeper challenges.

The Chinese Courtship: Munich’s Ironic Moment

Perhaps the most striking moment at Munich came when Chinese Foreign Minister Wang Yi championed the rules-based international order, free trade, and partnership over rivalry—rhetoric that once defined Western diplomacy. For Singapore, this role reversal carries profound implications.

Singapore has historically positioned itself as a champion of the rules-based order and ASEAN-centered multilateralism. The city-state’s prosperity depends on open sea lanes, predictable trade rules, and respect for international law. When Beijing sounds more committed to these principles than Washington, Singapore faces a disorienting strategic landscape.

Yet Wang Yi’s actual behavior reveals the limits of Chinese rhetoric. When pressed on Beijing’s role in ending the Ukraine conflict, he remained deliberately non-committal. More relevant to Singapore, China’s actions in the South China Sea directly contradict its stated commitment to international law. Despite the 2016 Permanent Court of Arbitration ruling that invalidated China’s nine-dash-line claims, Chinese coast guard vessels entered Malaysian waters near Sabah and Sarawak every single day between January and September 2025. The Philippines, ASEAN’s 2026 chair, faces escalating confrontations with Chinese vessels using water cannons and ramming tactics.

Singapore’s Defense Minister Chan Chun Sing, speaking at Munich, emphasized that Singapore must strengthen networks of friends and partners through mechanisms like the Five Power Defence Arrangements. His assertion that “strong fences—and I would add, defenses—make good neighbors” reflects Singapore’s enduring belief that military deterrence remains essential even as diplomatic engagement continues.

The Budget Reality: Singapore’s Defense Expansion

Singapore’s defense spending represents approximately 3% of GDP, with Defense Minister Ng Eng Hen announcing in March 2025 that this rate would be maintained while the country embarks on significant capability upgrades. This positions Singapore as Southeast Asia’s largest defense spender in absolute terms, though its economy is considerably smaller than Indonesia’s.

The 2025 defense budget prioritizes several key areas:

Naval Expansion: Two additional Type 218SG Invincible-class submarines from thyssenkrupp Marine Systems will bring the fleet to six vessels. These German-built submarines enable extended underwater operations in tropical waters—a capability essential for a maritime nation facing an increasingly contested littoral environment.

Artillery Modernization: Singapore’s 24 HIMARS launchers will receive midlife upgrades enabling them to fire the Army Tactical Missile System and Precision Strike Missile, significantly extending their range and precision.

Counter-Drone Capabilities: A new Counter-UAS Development and Operations group will develop concepts and field sensors, jammers, and weapons to address the proliferation of unmanned aerial systems—a threat demonstrated vividly in Ukraine and increasingly relevant to asymmetric conflicts.

Cyber Defense: The establishment of Defence Cyber Command recognizes that modern warfare extends well beyond kinetic domains. Singapore’s small geographic size and dense urban infrastructure make it particularly vulnerable to cyber attacks targeting critical infrastructure.

These investments reflect what analyst Collin Koh described as a response to “the evolving security landscape—increasingly fraught, uncertain and all the more so when international rule of law is coming under strain.” Notably, these acquisitions proceed from “quickness in buying rather than threat-based planning”—suggesting that Singapore views the current window for defense procurement as particularly favorable before geopolitical conditions deteriorate further.

The Alliance Calculation: Europe’s Lessons for Singapore

The Munich conference revealed European leaders attempting to demonstrate their value to Washington through a logic of strategic indispensability. German Chancellor Friedrich Merz, speaking in English to ensure American audiences understood, emphasized that “NATO is not only our competitive advantage but, dear American friends, yours too.”

This argument—that alliances multiply American power rather than burden it—finds scholarly support. Sixteen former U.S. ambassadors to NATO and Supreme Allied Commanders argued that “NATO is not an act of American generosity. It is a strategic bargain that ensures the United States remains the world’s most powerful and economically secure nation at a fraction of the cost of going it alone.”

Singapore employs similar logic. The city-state provides the United States with strategic access to Southeast Asia at minimal cost. Changi Naval Base serves as a critical logistics hub for the U.S. Navy. P-8A Poseidon maritime surveillance aircraft operate from Singapore, securing the “base leg” of American maritime patrol coverage in the South China Sea. The arrangement allows Washington to project power throughout Southeast Asia without the expense and political complications of a permanent military presence.

Yet Europe’s experience suggests the limitations of this argument when facing a president who views alliances through a purely transactional lens. Trump’s demand that NATO members spend 5% of GDP on defense by 2035 came with the implicit threat that anything less makes the alliance expendable. Singapore already exceeds NATO’s previous 2% target, but the goalposts continue shifting.

The ASEAN Conundrum: Collective Security in a Divided Region

Singapore’s security strategy relies heavily on ASEAN cohesion and the bloc’s ability to shape regional security architecture. Yet ASEAN faces deepening internal divisions, particularly over the South China Sea Code of Conduct negotiations with China.

As of February 2026, the Philippines, serving as ASEAN chair, announced plans to accelerate Code of Conduct negotiations to monthly working group meetings. Philippine Foreign Secretary Theresa Lazaro expressed optimism about concluding the agreement by the July 2026 deadline established in 2023. However, analysts remain skeptical. Fundamental disagreements persist over whether the code should be legally binding, its geographic scope, and definitions of key terms like “self-restraint.”

The slow pace of ASEAN-China negotiations works to Beijing’s advantage. While talks continue, China steadily consolidates its physical presence in disputed waters. ASEAN’s consensus-based decision-making means that any single member state can block progress—a vulnerability China has historically exploited by cultivating bilateral relationships with individual ASEAN members.

For Singapore, which has no territorial claims in the South China Sea, the priority is maintaining freedom of navigation and upholding the principle that might does not make right. Speaking at Munich, ASEAN Secretary General Kao Kim Hourn described both the U.S. and China as “comprehensive strategic partners” of the bloc, emphasizing that both powers “can contribute positively provided we have the shared understanding of the framework.”

This careful balancing act—maintaining productive relationships with both Washington and Beijing without choosing sides—has served Singapore well. But the Munich conference suggests this strategy faces mounting pressure as great power competition intensifies and middle options narrow.

The European Defense Industry Crisis: Lessons for Regional Collaboration

The Munich conference exposed Europe’s failure to translate security anxieties into effective defense industrial collaboration. Despite Russia’s full-scale invasion of Ukraine four years ago and mounting concerns about American reliability, European defense cooperation remains paralyzed by national rivalries.

The Franco-German FCAS (Future Combat Air System) fighter jet project epitomizes these failures. Talks between Airbus and Dassault have stalled over French insistence on maintaining industrial leadership. Former NATO General Erhard Buhler warned this would be “a fatal signal if the two largest European countries were unable to reach an agreement.”

Europe’s defense market remains fragmented across national champions. Only five European companies rank among the world’s top 20 defense manufacturers: BAE Systems, Leonardo, Airbus, Thales, and Rheinmetall. By contrast, five American defense giants—RTX, Lockheed Martin, Boeing, General Dynamics, and Northrop Grumman—dominate the sector globally.

This fragmentation offers sobering lessons for Southeast Asian defense collaboration. ASEAN members collectively spent $43 billion on defense in 2021—merely 2% of worldwide expenditure. Individual procurement decisions often prioritize national industrial benefits over regional interoperability. Thailand has ordered submarines from China, Singapore procures from the United States and Germany, Indonesia pursues French and Korean systems, while the Philippines has turned to South Korea for fighter aircraft.

The absence of defense industrial coordination means ASEAN militaries operate incompatible systems with minimal interoperability—precisely the weakness that has plagued European defense for decades. Unlike Europe, ASEAN lacks the institutional mechanisms or political will to pursue defense industrial integration.

Singapore’s Strategic Responses: Pragmatic Adaptation

Singapore’s response to the changing security environment reflects characteristic pragmatism tempered by realism about the city-state’s limited capacity to shape major power dynamics.

Diversification Without Abandonment: Singapore continues deepening defense ties with the United States while expanding cooperation with other partners. The Enhanced Defense Cooperation Agreement with Washington coexists with growing defense relationships with France, Germany, India, and fellow ASEAN members through the Five Power Defence Arrangements.

Technology Sovereignty Where Feasible: Singapore’s defense industrial base produces locally designed armored vehicles, artillery systems, and naval vessels. ST Engineering participates in the global F-35 supply chain, providing components and support services that generate economic returns while building domestic aerospace expertise. However, Singapore cannot realistically achieve full technology sovereignty in areas like fighter aircraft or advanced sensors where development costs exceed what a small nation can justify.

Regional Leadership Through Example: Singapore consistently advocates for ASEAN unity while acknowledging the bloc’s limitations. By maintaining defense spending at 3% of GDP and fielding Southeast Asia’s most technologically advanced military, Singapore demonstrates that small states can achieve credible deterrence through sustained investment and professional excellence.

Economic Hedging: Singapore’s economy remains deeply integrated with both the United States and China. American companies employ over 250,000 workers across more than 30 U.S. states through investments and trade relationships. Simultaneously, China represents Singapore’s largest trading partner. This economic interdependence constrains both powers’ ability to demand exclusive alignment.

The Darkening Horizon: What Singapore Faces

The Munich Security Conference of 2026 revealed an international order under profound stress. For Singapore, several worst-case scenarios merit serious consideration:

Scenario One: American Retrenchment: If the United States continues prioritizing hemisphere dominance over global leadership, Singapore could face a security vacuum in Southeast Asia. China would likely fill this void, potentially transforming the South China Sea into a Chinese lake. Freedom of navigation—the lifeblood of Singapore’s economy—could become contingent on Beijing’s goodwill rather than international law.

Scenario Two: Forced Choices: As great power competition intensifies, Singapore’s careful balancing act may become untenable. Both Washington and Beijing might demand exclusive alignment, forcing Singapore to sacrifice one relationship to preserve the other. Either choice would undermine Singapore’s prosperity and security.

Scenario Three: Regional Fragmentation: ASEAN’s inability to maintain cohesion could leave Singapore diplomatically isolated. If maritime Southeast Asian states cannot coordinate responses to external pressure, China could employ divide-and-conquer tactics that leave individual states vulnerable to coercion.

Scenario Four: Technology Decoupling: Comprehensive separation of American and Chinese technology ecosystems could force Singapore to choose which standards, systems, and supply chains to adopt. This would be particularly damaging for Singapore’s role as a regional technology and financial hub serving both spheres.

Navigating Uncertainty: Singapore’s Path Forward

The Munich conference confirmed that the post-Cold War era of American-led globalization has definitively ended. For Singapore, which prospered under that system, the emerging multipolar disorder presents existential challenges.

Several principles should guide Singapore’s adaptation:

Maintain Defense Primacy: Continued investment in military capabilities remains essential. Singapore’s small size and strategic location make it perpetually vulnerable to coercion. Only credible defense prevents larger neighbors or distant powers from viewing Singapore as merely an asset to be controlled.

Expand Strategic Relationships: Over-dependence on any single partner creates vulnerability. Singapore must continue diversifying defense partnerships, technology sources, and diplomatic relationships. The Five Power Defence Arrangements, bilateral defense agreements with France and India, and ASEAN mechanisms all provide additional insurance against American unreliability.

Champion Rules and Norms: As a small state, Singapore has outsized interests in preserving international law and multilateral institutions. When great powers abandon these principles, small states lose their primary protection against predation. Singapore must continue advocating for the rules-based order even when major powers find it inconvenient.

Prepare for Economic Turbulence: The Munich conference demonstrated that trade relationships are increasingly weaponized. Singapore must build economic resilience through diversification, strategic reserves, and maintaining flexibility to adapt supply chains as geopolitical winds shift.

Invest in National Unity: External threats can only be effectively countered by internally cohesive societies. Singapore’s multiracial, multireligious society represents both a strength and potential vulnerability. Continued investment in social cohesion and national identity becomes more critical as external pressures mount.

Conclusion: Small State Survival in an Age of Giants

The Munich Security Conference of 2026 will be remembered as the moment when Europeans explicitly confronted American unreliability. For Singapore, observing from halfway around the world, the lesson is clear: the alliance structures and international norms that enabled small state prosperity cannot be taken for granted.

Singapore faces this uncertain future from a position of relative strength. The city-state maintains Southeast Asia’s most capable military, a sophisticated defense industry, deep relationships with multiple major powers, and a strategic location that gives it inherent value to competing powers. Singapore’s economic dynamism and political stability provide resources for adaptation.

Yet structural realities impose harsh constraints. Singapore’s small size limits its defense industrial base. Its dependence on trade makes it vulnerable to economic coercion. Its location in a region contested by great powers means it cannot escape the consequences of their rivalry. And its informal security arrangements lack the certainty that treaty alliances theoretically provide—though Munich demonstrated that even formal alliances offer limited guarantees.

The smiles at Munich masked a fundamental crisis in the Western alliance system. For Singapore, the challenge is to navigate this crisis without illusions about its ability to control outcomes, but with clear-eyed determination to preserve its sovereignty, prosperity, and way of life. The path forward requires strategic patience, tactical flexibility, and the recognition that small states survive not by choosing the right great power patron, but by making themselves too valuable to coerce and too difficult to conquer.

As the international order fragments, Singapore’s founding generation’s conviction rings ever more relevant: that small states can survive only through excellence, deterrence, and the wisdom to distinguish between what can be changed and what must be endured. The Munich conference of 2026 suggests that the coming years will test these principles as never before.
