U.S. Secretary of State Marco Rubio reaffirmed Washington’s commitment to NATO after questions about Russian missile deployments to Belarus and European concerns over security. Responding to fears voiced by European leaders, Rubio said NATO remains the cornerstone of stability in Europe and a strong deterrent against potential aggression. He stressed that the United States backs its commitments with troops, funding, and daily cooperation, not just rhetoric. Rubio said Article 5 remains central to collective defence and insisted the alliance is active and united. He added that Washington wants European allies to strengthen their own capabilities to make NATO even stronger.
