Europe discusses independent nuclear arsenal following US intelligence pause in March 2025

In March 2025, the United States briefly suspended intelligence sharing with Kyiv regarding the war in Ukraine, leading to significant battlefield setbacks for Ukrainian forces. This incident prompted European allies to question the reliability of Washington as a military partner and look for strategic alternatives. For the first time since the Cold War, European capitals are discussing the development of an independent nuclear arsenal to enhance continental autonomy. Currently, European security relies on the American nuclear umbrella and NATO mutual defense agreements. Only France and the United Kingdom currently possess nuclear weapons within Europe. Reports from Bloomberg, citing government and military sources, indicate that French President Emmanuel Macron is expected to offer a French nuclear umbrella to the continent. The shift comes as European nations accelerate rearmament efforts while attempting to maintain US involvement in NATO. Ultimately, the potential loss of US reliability has forced leaders to consider a sovereign deterrent against Russia.
