**Congressional restrictions and procedural hurdles continue to constrain any U.S. withdrawal from NATO despite periodic administration rhetoric.** Legislation enacted in the 2024 National Defense Authorization Act requires Senate advice and consent or an act of Congress before the president can issue a notice of denunciation under Article 13 of the North Atlantic Treaty, which itself mandates a one-year waiting period after formal notification. As of mid-June 2026, no such notice has been delivered. Recent tensions following the Iran conflict prompted public discussion of withdrawal and led to announced U.S. troop reductions in Germany plus plans to redirect long-range strike assets, yet these steps reflect pressure for greater European burden-sharing rather than alliance exit. A 2027 target for Europe-led conventional defense has been signaled internally, but formal treaty termination remains blocked without legislative approval. Trader consensus reflects these structural barriers and the absence of imminent congressional action.
