NATO's Biggest Challenges in 2025: A Clear-Eyed Look
The alliance faces mounting pressure on defense spending, unity, and strategy as global threats multiply and U.S. commitment wavers.
NATO, the 75-year-old transatlantic military alliance binding 32 member nations, is navigating one of its most turbulent stretches since the Cold War ended, with disagreements over burden-sharing, the war in Ukraine, and shifting U.S. foreign policy priorities all converging at once.

The stakes could not be higher for an organization whose foundational Article 5 collective-defense guarantee depends as much on perceived credibility as on military hardware. Continue reading at Reuters.
