Tensions within NATO center on U.S. demands for higher European defense spending and direct support in the Iran conflict, particularly naval efforts to reopen the Strait of Hormuz. In April 2026, President Trump publicly criticized allies for limited involvement and labeled the alliance a "paper tiger," prompting announcements of U.S. troop reductions in Germany and discussions of a 2027 deadline for Europe to assume primary conventional defense roles. No member state has initiated formal withdrawal procedures, and U.S. law requires two-thirds Senate approval or congressional action to exit the treaty. European capitals are advancing contingency plans for greater self-reliance while reaffirming collective defense commitments under Article 5. These dynamics, combined with scheduled alliance consultations through 2027, shape trader assessments of near-term departures.
