The fracture between Washington and its European allies deepens week by week. Spain closed its bases and airspace to American aircraft linked to operations against Iran. Italy followed by refusing the Sigonella base, while Germany debates the legality of using Ramstein. Trump responded by calling NATO a "paper tiger" and raising the prospect of a US withdrawal from the alliance. The UK is calling for autonomous European defense, while Canada has finally reached the 2% GDP threshold for military spending. For the first time since NATO's creation, the question is no longer whether the alliance will hold, but in what form.

Link between the Merz-Trump dispute and the troop withdrawal
Merz says there is 'no connection' between his criticism of US Iran strategy and the withdrawal decision. A senior anonymous Pentagon official says the exact opposite: German rhetoric was 'inappropriate and counterproductive.' Washington sees the decision as a legitimate response; Berlin tries to minimize the damage to preserve the relationship.
Significance for deterrence against Russia
Republican armed services committee chairs (Wicker, Rogers) warn that reducing US presence in Europe risks sending the 'wrong signal to Putin.' Ukraine is directly concerned. Germany tries to compensate by accelerating rearmament. Moscow sees the withdrawal as confirmation that the Western alliance is fracturing.
The withdrawal of 5,000 US soldiers from Germany — 14% of the 36,000 US military personnel stationed there — comes amid multiple tensions: disagreement over Iran strategy, 25% tariffs on European cars, and European refusal to actively support the war. Trump used this decision as diplomatic punishment, but its reach goes much further: the cancellation of Tomahawk missiles concretely weakens Western strike potential in Eastern Europe, and the signal sent to Moscow worries even congressional Republicans.
