Europe strengthens defence amid US tensions, a message that dominated discussions at this year’s Munich Security Conference. European Commission President Ursula von der Leyen captured the mood by saying, “Some lines have been crossed that cannot be uncrossed anymore.” Her words reflected growing concern among European leaders about the future of transatlantic relations.
Over the past year, ties between Europe and the United States have faced increasing strain following Donald Trump’s return to the White House. His remarks about annexing Greenland further intensified doubts across Europe about Washington’s long-term commitment to NATO and continental security.
U.S. Secretary of State Marco Rubio sought to reassure European allies during his speech in Munich. He emphasised cooperation and used a warmer tone than Vice President JD Vance had in previous remarks. However, Rubio did not address NATO directly, nor did he reference Russia or the war in Ukraine issues central to European security debates.
As the war in Ukraine approaches its fifth year, many European governments view Moscow as an escalating threat. In response, leaders pledged to accelerate efforts to reinforce their own defences and reduce reliance on the United States.
Europe Strengthens Defence Amid US Tensions Through NATO Reform
European leaders signalled a renewed commitment to building what they called a stronger “European pillar” within NATO. German Chancellor Friedrich Merz, French President Emmanuel Macron, and British Prime Minister Keir Starmer each voiced support for deeper European defence cooperation.
Merz described the shift as necessary under any circumstances. Whether the United States distances itself further or maintains current commitments, he argued, Europe must be prepared to guarantee its own security.
In another notable development, Merz confirmed that he had begun discussions with Macron about a potential European nuclear deterrence framework. France currently holds the only fully independent nuclear deterrent in Europe, as Britain’s Trident system relies on U.S. manufacturing and maintenance.
At the same time, the U.S. administration has said it expects Europe to assume primary responsibility for conventional defence. Washington has indicated it will maintain its nuclear umbrella and uphold NATO’s mutual defence pact.
Despite political tensions, defence spending across Europe has risen sharply. NATO members agreed to increase core defence spending from 2% of GDP to 3.5%, with an additional 1.5% allocated to broader security investments. Von der Leyen stated in Munich that European defence spending has risen nearly 80% since before the war in Ukraine began.

— WORLD NEWS (@_MAGA_NEWS_) February 14, 2026Several new initiatives are underway. Defence ministers from France, Germany, Italy, Poland, and Sweden signed a letter of intent to advance the European Long-range Strike Approach (ELSA), which aims to develop deep-strike missile capabilities. Meanwhile, additional coalitions agreed to collaborate on ballistic missile defence and air-launched munitions.
However, challenges remain. Some high-profile joint projects have struggled to move forward. The Future Combat Air System (FCAS), a French-German-Spanish fighter jet initiative, has faced delays due to disagreements over industrial work-sharing arrangements.
Debates have also emerged within the European Union over procurement rules. France has advocated for stronger “buy European” provisions, while countries such as Germany and the Netherlands favour a more open defence market.

Against this backdrop, Ukrainian President Volodymyr Zelenskiy reminded delegates of the war’s urgency. Speaking before screens displaying images and statistics of Russian attacks, he highlighted the rapid evolution of modern warfare. Last month alone, Ukraine faced more than 6,000 drones and 150 missiles.

His remarks underscored the central dilemma confronting Europe. While political declarations signal unity, implementation remains complex. Leaders must translate pledges into coordinated procurement, industrial cooperation, and operational readiness.
Ultimately, Europe strengthens its defence amid US tensions not only in response to geopolitical friction but also as a strategic recalibration. Whether this shift results in lasting structural change will depend on sustained political will and practical follow-through. [Internal link: Latest updates on the Russia-Ukraine war]
