Trump’s threat to pull the United States out of NATO doesn’t just rattle diplomats; it shakes the foundation of the entire post‑war order. For decades, the alliance has rested on the assumption that Washington would always be there, no matter how bitter the arguments. By calling NATO a “paper tiger” and accusing Britain and France of freeloading or cowardice, Trump is turning that assumption into a question mark.
His attacks cut especially deep because they come amid a brutal conflict with Iran, when unity would normally be the West’s greatest asset. Instead, he is publicly humiliating partners, mocking Britain’s navy, and accusing France of blocking vital support to Israel. Whether this is hard‑ball negotiation or a genuine desire to walk away, the damage is real: trust is eroding, and adversaries are watching. NATO may survive, but it will not emerge unchanged.
