Trump Threatens NATO Exit Over Iran War Support Rift

President Donald Trump has threatened to withdraw the United States from NATO, labeling the alliance a "paper tiger" and claiming it "turned their backs on the American people." The crisis stems from a military campaign against Iran and Israel that began in February 2026, during which several European allies—including France, Spain, and the United Kingdom—restricted U.S. access to military bases and airspace and refused to deploy warships to reopen the Strait of Hormuz.

Following a tense meeting at the White House on April 8, Trump intensified his rhetoric, suggesting a full rupture of ties. He also linked his dissatisfaction to Denmark's refusal to cede Greenland to the U.S., describing the territory as a "big, poorly run, piece of ice." While Trump indicated withdrawal is "beyond reconsideration," legal experts and lawmakers noted that a 2023 law requires an act of Congress or a two-thirds Senate majority for a formal exit.

In response, the Trump administration is considering punitive measures, including the redeployment of U.S. troops from "unhelpful" nations like Germany, Italy, and Spain to more cooperative allies such as Poland and Romania. NATO Secretary-General Mark Rutte has attempted to mollify Trump by praising his leadership and urging European nations to increase defense spending to a 5% GDP benchmark to reduce "unhealthy codependence.

European leaders have reacted with a mix of defiance and anxiety. Some are pivoting toward "strategic autonomy" and developing a "European NATO" fallback plan. Despite the volatility, Rutte maintains that the U.S. nuclear umbrella remains the ultimate guarantor of European security.
