NATO's Future: Can Alliance Survive US Pullout?

Why it matters: The US could move 84,000 American troops out of Europe, damaging NATO's security guarantees.
- Donald Trump's disdain for NATO allies, stemming from low defense spending and recent threats concerning Greenland, has been exacerbated by their non-participation in the war in Iran.
- Chancellor Friedrich Merz of Germany described the conflict as a "trans-Atlantic stress test," echoing Trump's sentiment that allies' lack of support is a "stain on the alliance."
- Jim Townsend of the Center for a New American Security believes there will be no return to "business as usual in NATO," signaling a potential permanent shift in the alliance's dynamics.
- Trump cannot unilaterally withdraw the US from NATO without a two-thirds Senate majority or an act of Congress, but he can undermine the alliance by withdrawing troops or ceasing military coordination.
- Stefano Stefanini, former Italian ambassador to NATO, notes that Trump has already "eroded its credibility as an effective alliance" simply by suggesting a potential US withdrawal.
The war in Iran has intensified long-standing tensions within NATO, with President Trump's criticism of allies' lack of support deepening the rift to unprecedented levels. Analysts like Jim Townsend and former Italian Ambassador Stefano Stefanini warn that the alliance is "closer to a break than ever," questioning its survival, especially if the US disengages without formally withdrawing.
