End of multilateralism: Iran war exposed NATO's irrelevance - opinion

For decades, the North Atlantic Treaty Organization (NATO) has been exalted as the unshakeable bedrock of Western security. Forged in the crucible of the Cold War to repel totalitarian expansion, it was long considered the ultimate deterrent. Yet, when the geostrategic landscape violently shifted in early 2026 – as a ring of fire closed around the Jewish state and the Iranian regime escalated its proxy wars into direct, kinetic assaults on Western interests – that vaunted shield did not merely fracture.

It vanished. The resounding silence echoing from Brussels following Israel's necessary, preemptive strikes on Iranian military infrastructure represents far more than a transient diplomatic lapse. It is the definitive death certificate of multilateralism and irrefutable proof that the alliance has rendered itself strategically irrelevant against the defining threat of our age.

The events of February and March 2026 laid bare the hollow core of the post-World War II order. Iranian forces and their proxies had long destabilized the region, with Hezbollah raining rockets on Israel's northern frontier and Houthis disrupting vital Red Sea shipping lanes. When the Islamic Republic escalated to direct strikes, Israel acted as any sovereign, self-respecting nation must: it struck decisively to neutralize an immediate, existential danger.

Washington provided critical operational and diplomatic support. NATO, however, offered nothing beyond vague statements from Secretary-General Mark Rutte – passing praise heavily conditioned by a frantic insistence that the alliance would not be drawn into the fray.

The myth of collective securityMultilateralism was long peddled to Western policymakers as the ultimate force multiplier. It promised a grand union of democratic nations capable of presenting a united front against shared dangers, theoretically offering the profound benefits of collective security without the heavy political burdens of unilateral action. In practice, however, when confronted by the existential threat of Islamist aggression and a hostile state in Tehran, Europe has reflexively retreated into a posture of studied neutrality.

That neutrality is simply a courteous euphemism for strategic timidity and moral abdication.

Consider the alliance's historical trajectory. Following the collapse of the Soviet Union, NATO expanded eastward and intervened in the Balkans. Yet, its post-9/11 operations in Afghanistan culminated in a humiliating withdrawal that telegraphed Western weakness to adversaries globally.

The 2011 Libya campaign, once hailed as a multilateral success, descended into chaos that fueled migration crises and jihadist safe havens across North Africa. Today, with Iranian ballistic missiles not only targeting Israel but theoretically capable of threatening European bases and energy infrastructure, the alliance's response is telling. Instead of projecting deterrence, NATO offers endless debates in Brussels about legal niceties while individual members prioritize domestic politics over collective survival.

The illusion of European strategic autonomyThe current conflict has violently torn away the last lingering illusions of a cohesive global partnership, revealing a stark truth: Israel and the United States are operating as the sole credible guardians of Western civilization in the Middle East.

Continental powers, particularly France and Germany, remain severely constrained by their own myopic policy choices. Their historical reliance on Russian natural gas has simply been replaced by a desperate hedging strategy involving Middle Eastern autocrats and the appeasement of Tehran.

Furthermore, domestic political calculations – shaped by large immigrant populations sympathetic to the ideologies fueling Iran's aggression – further tie their hands. Their much-touted pursuit of “strategic autonomy” has ultimately manifested as a deliberate refusal to acknowledge reality. They fail to recognize that the front line of their own defense is currently being held by the IDF.

Strategic obsolescence and the end of an eraEndorsing Israel's sovereign right to strike the fountainhead of regional and global terrorism should have been the baseline requirement for any serious defense alliance. NATO's effective refusal to do so demonstrates a fatal flaw: the organization no longer possesses the clarity to recognize its own enemies.

An alliance incapable of identifying the primary, active threat to its members' fundamental way of life has devolved into a historical artifact. Designed to halt Soviet armor on the plains of Europe, NATO has proven itself utterly unprepared for the asymmetric, ideological, and proxy-driven warfare of the 21st century – a battlespace where missiles fly from Tehran, and terrorists operate with impunity from Beirut to Sanaa.

We are witnessing the final unraveling of the post-World War II security architecture. The United Nations long ago degenerated into a theater for autocratic grandstanding and anti-Western diatribes. The Atlantic alliance now risks becoming a debating club for retired generals and diplomats more concerned with achieving consensus than achieving victory.

The age of seeking lowest-common-denominator agreements among the reluctant is over. If Western civilization is to survive the rising tide of radical aggression, it will not be secured by another European summit communiqué. It will endure solely because nations like Israel demonstrated the unflinching courage to act when necessary, backed by the only ally that still comprehends the indispensable grammar of hard power.
