Europe's Defense at a Crossroads: The Growing Gap Between Ambition and Reality

The European defense policy is undergoing an unprecedented upheaval in April 2026. The simultaneous crises — the ongoing Russian war of aggression against Ukraine, the U.S.-led war against Iran, and the increasingly fragmented transatlantic relations — are forcing decisions that would have been considered unthinkable just a few years ago. However, there is a troubling gap between political declarations of intent and military reality that has widened significantly.

EU Defense Commissioner Andrius Kubilius renewed his call for a common European army in a remarkable interview with POLITICO on April 10, providing a clear diagnosis: mere coordination of 27 national armies is insufficient to ensure the continent's defense capability. His statements are further underscored by the results of the European Pulse survey conducted by Cluster17 for POLITICO and beBartlet between March 13 and 21. Of the 6,698 respondents in Belgium, France, Germany, Italy, Poland, and Spain, only 35 percent rated the United States as a close ally or partner, while 60 percent viewed the country as a competitor or threat. At the same time, 86 percent support the expansion of independent European defense capabilities, and 69 percent favor the creation of a common European military force. These figures document a fundamental loss of trust in the transatlantic security architecture.

The causes of this loss of trust are diverse and cumulative. The meeting between NATO Secretary General Mark Rutte and President Donald Trump on April 9 ended with a public humiliation of the alliance. Trump accused European allies of abandoning the United States in the Iran conflict and subsequently posted the devastating statement on Truth Social that NATO was not there when it was needed. The background is the refusal of European governments to allow the United States to use their military bases for attacks against Iran. The resulting question of whether the NATO mutual defense clause would even apply in the event of an American war of aggression has sparked a debate that shakes the foundation of the alliance.

This sentiment is echoed in the stance of the new Hungarian opposition leader Péter Magyar, who announced a fundamental realignment of Hungarian defense policy following the ousting of Viktor Orbán. Magyar aims to increase defense spending, combat industrial corruption in the arms sector, and regain the trust of NATO allies. His initiative is symptomatic of a broader trend: domestic political conditions in Europe are shifting in favor of forces demanding stronger European defense integration.

However, the practical obstacles remain enormous. The most prominent example currently comes from Germany. Berlin's two billion euro system for digitizing the battlefield, a key project of the Bundeswehr reform, has encountered difficulties that raise fundamental questions about Germany's armament capability. The project, which is intended to enable networked operations of modern armed forces, is struggling with technical problems and now requires additional funding. This is all the more alarming as Germany, as the largest economy in the EU and a NATO treaty partner, should be taking a leading role in modernizing European armed forces.

The United Kingdom, despite Brexit, remains a central European NATO partner and faces similar dilemmas. Prime Minister Keir Starmer is grappling with how to finance his country's ambitious armament goals without touching the social system. The strategic necessity of military rearmament stands in painful contrast to the budgetary reality. At the same time, London has established a crisis team structured after the Brexit preparations and the Covid-19 pandemic to manage the Iran conflict, the so-called Middle East Response Committee. This measure underscores that the British government perceives geopolitical upheavals as an immediate security policy challenge.

Meanwhile, the threat landscape on NATO's eastern flank is worsening due to hybrid attacks. The Estonian intelligence service KAPO has reported a record number of uncovered Russian spies and warns that non-military threats — sabotage, espionage, and information campaigns — are gaining increasing significance. This development underscores that the European security architecture requires not only conventional armed forces but also robust defense mechanisms against hybrid warfare.

The global political dynamics further intensify the pressure for action. Russia's major assault on Ukraine on the night of April 16, which involved nearly 700 drones and 44 missiles and resulted in at least 16 deaths, demonstrates the ongoing brutality of the war. At the same time, Ukrainian President Volodymyr Zelensky reported a historic milestone: robots have captured Russian positions for the first time without infantry support, forcing the occupiers to surrender. This development points to a revolution in warfare that also presents new challenges for European defense planning.

Italy, under Prime Minister Giorgia Meloni, has suspended the renewal of its defense agreement with Israel, signaling a foreign policy realignment in the Middle East. France and the United Kingdom have announced plans to coordinate discussions on securing the Strait of Hormuz, and Germany has indicated it will provide mine-hunting vessels — a sign that European powers are increasingly willing to take on security responsibilities beyond their own continent.

The overall balance is mixed. On one hand, there is an unprecedented political will to strengthen European defense, supported by a population that largely favors a common military force. On the other hand, failed digitization projects, unresolved funding issues, and the continuation of national unilateral actions reveal the structural weaknesses of the European approach. The question of whether Europe can close the gap between ambition and reality before the next crisis tears it open remains the decisive security policy challenge of our time.
