The US has announced a withdrawal of 5,000 soldiers from Germany, its largest military base in Europe, further straining relations with European allies amid ongoing disputes over the Iran war and tariffs. This troop presence, which has historically been a deterrent against threats such as Russia, has seen a significant reduction since the Cold War, when approximately 320,000 US troops were stationed in Europe. Currently, around 40,000 troops remain in Germany, including personnel at key facilities like Ramstein Airbase and Landstuhl hospital, which support US military operations globally.

President Donald Trump’s decision follows criticisms from German Chancellor Friedrich Merz regarding US foreign policy. The withdrawal could undermine NATO's collective defense framework and push Europe to enhance its own military capabilities. German Defense Minister Boris Pistorius emphasized the need for Europe to take greater responsibility for its security, with plans to increase the Bundeswehr's active-duty personnel significantly. The EU is also exploring a mutual assistance pact, which could shift reliance from NATO’s Article 5 to Article 42.7 of the Treaty on European Union, indicating a move towards a more autonomous European defense strategy.
