President Trump's ultimatum to NATO allies to secure the Strait of Hormuz within days threatens to fracture the 77-year-old alliance.

US President Donald Trump has demanded NATO allies produce “concrete plans” within days to secure the Strait of Hormuz, through which 20 percent of the world’s oil passes, escalating tensions within the alliance and risking further turmoil in global energy markets. The ultimatum follows a tentative US-Iran ceasefire after a conflict that shut down the vital trade corridor and comes with threats of US troop withdrawals from European countries deemed unsupportive.
"We note the frustration in Washington, but they did not consult allies either before or after starting this war," one European diplomat told Reuters, highlighting the deep divisions. In a more conciliatory tone, NATO Secretary General Mark Rutte, known as the "Trump Whisperer," acknowledged the president's position, stating after a meeting with Trump that he "is clearly disappointed with many NATO allies, and I can see his point."
The demand puts pressure on a 40-country coalition, led by the UK, that had pledged to help reopen the waterway once hostilities ceased. However, the fragile 14-day ceasefire between the US and Iran is already strained, with continued exchanges of fire between Iran and Israel. After his meeting with the 32-member alliance, Trump posted on Truth Social that "NATO WASN’T THERE WHEN WE NEEDED THEM, AND THEY WON’T BE THERE IF WE NEED THEM AGAIN."
The standoff places the future of the transatlantic security alliance under severe strain, with markets bracing for potential oil price shocks if the strait remains closed. With the US considering redeploying troops from allies like Germany, France, and Spain, the crisis is evolving from a regional conflict into a test of NATO's fundamental cohesion, carrying significant implications for European security architecture and US global military posture.
In a spirited address following his meeting with Trump, NATO's Rutte called out European allies for an “unhealthy codependence” on US security guarantees that dates back decades. “[They were] so convinced that peace was permanent and didn’t demand the investment we now know is essential,” Rutte said at the Reagan Institute, noting that European defense budgets had “shriveled into irrelevance.”
The comments represent a direct acknowledgment of Trump's long-held criticism that fellow NATO members have failed to bear a fair share of the collective defense burden. While Rutte attempted to reassure audiences that Europe is now increasing its defense spending, particularly since the war in Ukraine, Trump's public frustration suggests his patience is wearing thin. The US is reportedly considering pulling troops from countries that were "lacking in assistance" during the Iran conflict, including Germany, France, Spain, and Italy, and redeploying them to more supportive nations.
The crisis exposes deep fractures within NATO. French officials have stated they can no longer hold the same level of trust in US security commitments, with one former army officer noting Trump discusses the alliance "as if the United States were not a member." Germany has faced internal political calls to evict US troops, though the government has so far refused.
While a group of about 15 countries are reportedly planning to facilitate the resumption of traffic through the strait, French Foreign Minister Jean-Noel Barrot cautioned that a full reopening is impossible without a lasting US-Iran agreement. This leaves the 40-country naval coalition in a state of confusion, caught between a fragile ceasefire and Trump's demands for immediate action. The situation is a significant test for Rutte, who must now navigate the competing pressures of placating a volatile US president while maintaining unity among concerned European allies.
