BREAKING: European Allies Losing Hope of Keeping the United States in NATO Amid Trump’s Fury Over Iran War Support, The Economist Reports

European diplomats and leaders are increasingly losing hope that the United States will remain fully committed to NATO, according to a major report in The Economist. The growing pessimism stems from President Donald Trump’s escalating hostility toward European allies, driven by their refusal to provide meaningful military support for U.S. efforts to reopen the Strait of Hormuz during the ongoing Iran war.
The transatlantic rift has deepened dramatically in recent weeks. Trump has repeatedly criticized NATO as a “paper tiger” and a “one-way street,” threatened to pull the U.S. out of the alliance, and accused European nations of freeloading while America bears the brunt of operations against Iran. Several European countries have even complicated U.S. military activities in the Middle East, further fueling White House frustration.
“This is the worst moment that NATO has faced,” a former senior U.S. official told The Economist, highlighting fears that repeated threats are hollowing out the 77-year-old alliance even if formal withdrawal does not occur.
Root Cause: Europe’s Reluctance in the Iran Conflict
The immediate trigger is Europe’s limited involvement in the U.S.-Israeli campaign against Iran, which began in late February 2026. Trump has demanded that NATO allies deploy naval forces to help secure the Strait of Hormuz — a vital chokepoint carrying about 20% of global oil trade — after Iran disrupted shipping in retaliation for strikes.
European leaders have largely declined, citing legal concerns, domestic opposition, and reluctance to be drawn into offensive operations in the Middle East. UK Prime Minister Keir Starmer, French President Emmanuel Macron, and others have reaffirmed commitment to NATO’s collective defense under Article 5 but stopped short of direct support for the Iran mission.
Trump responded by labeling the alliance unreliable and warning that Europe would be “on its own” if it fails to assist. In interviews and Truth Social posts, he has mused about withdrawing U.S. forces or leadership from NATO, leaving Europeans to defend themselves against Russia or other threats.
European Reactions: Shock, Anxiety, and Strategic Planning
European capitals are reacting with a mix of shock, anxiety, and accelerated planning for a post-American security architecture:
- Germany and France: Leaders have expressed concern that Trump’s rhetoric is eroding deterrence. Some officials privately admit they no longer fully trust U.S. security guarantees.
- Poland and Eastern Europe: More hawkish voices call for calm while pushing for higher defense spending, but even they worry about long-term U.S. commitment.
- UK: Prime Minister Starmer has described NATO as “the single most effective military alliance the world has ever seen” while quietly exploring closer European defense cooperation.
Many European diplomats now fear that even without a formal U.S. exit, America could effectively “defang” the alliance by reducing troop presence, intelligence sharing, or leadership roles. Discussions in Brussels and national capitals increasingly focus on European strategic autonomy — including independent command structures, rapid reaction forces, and massive increases in defense budgets.
Link to Broader Iran War Developments
This NATO crisis unfolds against intense military and diplomatic activity in the Middle East:
- President Trump has issued multiple 48-hour ultimatums to Iran (with recent adjustments setting a new target for April 7 at 8:00 PM ET), demanding the strait be fully reopened or a deal be reached, or “all hell will reign down.”
- Iran has rejected U.S. proposals linking Hormuz reopening to temporary ceasefires and warned that further escalation will turn the region into “hell” for America and Israel.
- U.S. forces continue strikes, depleting advanced munitions like JASSM-ER stealth missiles.
- Repeated incidents near Iran’s Bushehr Nuclear Power Plant have prompted Russian staff evacuations and warnings of regional radioactive risks.
- Iran maintains selective control over the strait, recently allowing 15 ships to pass with permission while exempting allies like Iraq.
Senator Lindsey Graham has strongly backed Trump, warning of a “massive military operation” if Iran does not comply.
Implications for Global Security
The erosion of trust in U.S. commitment to NATO comes at a precarious time, with Russia watching closely and China assessing long-term shifts in the international order. European leaders face pressure to dramatically boost defense spending, coordinate more closely within the EU, and reduce reliance on American security guarantees.
Legal experts note that a full U.S. withdrawal from NATO would require congressional approval and a one-year notice under Article 13, but Trump could still weaken the alliance significantly through reduced engagement.
As one European diplomat put it, non-European wars like the current Iran conflict have a history of straining NATO — from Suez to Iraq — but the current rift may prove more damaging than previous ones.
