Washington's NATO skepticism threatens alliance cohesion

The transatlantic alliance faces an existential test not from external adversaries but from internal doubt. A new Foreign Affairs analysis argues that Washington's growing dismissiveness toward NATO undermines the foundational trust that has sustained collective defense for seven decades.

The article frames trust as the alliance's operational currency. Without confidence that treaty obligations will be honored, deterrence loses credibility and member states hedge through unilateral arrangements. When the United States signals ambivalence—whether through rhetorical minimization of Article 5 commitments or transactional framing of burden-sharing—allies recalibrate their security postures accordingly.

This erosion carries compound effects. European capitals begin investing in autonomous defense capabilities, not as complements to NATO but as insurance against American unreliability. Defense industrial cooperation fragments. Intelligence-sharing becomes selective. The integrated command structure that enables rapid collective response atrophies through disuse and mistrust.
