The Trump administration has pursued incremental reductions in U.S. military commitments to NATO, including announced withdrawals of thousands of troops from Germany and Romania since late 2025, scaled-back fighter jets, bombers, tankers, and maritime assets assigned to the alliance, and a six-month force posture review launched in June 2026. These steps follow repeated presidential statements criticizing European allies over burden-sharing and support during the Iran conflict, alongside references to a transition toward greater European responsibility under a “NATO 3.0” framework. Formal U.S. withdrawal remains constrained by 2024 National Defense Authorization Act provisions requiring Senate advice and consent by a two-thirds vote or separate congressional authorization. Congressional oversight provisions in subsequent defense legislation and bipartisan resistance further limit unilateral action, while scheduled alliance summits and ongoing capability reviews continue to shape assessments of any near-term exit.
