The U.S.'s exit from NATO’s integrated military command structure will not be sufficient to resolve this market to "Yes". The resolution source will be official information from the US government and NATO, however a consensus of credible reporting may also be used.President Trump has repeatedly criticized NATO allies for insufficient defense spending and reluctance to support U.S. operations, such as in the Iran conflict earlier in 2026, prompting threats of withdrawal. However, a 2023 law embedded in the National Defense Authorization Act requires either a two-thirds Senate vote or an act of Congress for any U.S. exit from the alliance, creating a significant procedural barrier. At the July 2026 NATO summit in Ankara, Trump stated the United States would remain in the alliance. The administration has instead pursued troop reductions, fighter jet reallocations, and other force posture adjustments in Europe to shift more responsibility to allies. Congressional oversight provisions in recent defense bills and bipartisan resistance further constrain formal withdrawal options in the near term.
