Many of America’s traditional allies are entering a period of deep strategic anxiety: they are increasingly frustrated by what they see as erratic U.S. behavior under President Donald Trump, yet they also feel they have few realistic alternatives to American power. Friendly governments in Europe, Asia and the Middle East are being pushed into an uncomfortable position as the Iran war, tariff disputes and repeated political shocks from Washington strain relationships that were once treated as stable foundations of global order.
The immediate trigger is the widening Iran conflict and the economic fallout from it. The closure of the Strait of Hormuz has deepened the global energy crisis, hurting allied economies and exposing how dependent many countries remain on U.S. military choices and regional strategy. This crisis is on top of a broader year-long pattern of tension involving U.S. tariffs, disputes over support for Ukraine, and Trump’s remarks about Greenland, all of which have left allies questioning Washington’s reliability and judgment.
But the problem for U.S. allies is not simply disagreement with one policy, it is a growing fear that American foreign policy has become more unilateral, more personal and harder to predict. The Iran war is already straining the transatlantic alliance, with Trump criticizing NATO members for not supporting the U.S.-Israeli campaign strongly enough and even threatening to withdraw from the alliance. NATO Secretary General Mark Rutte acknowledged on April 8 that some European allies “were tested and failed,” though he said most had still provided support in ways they had pledged. Together, those developments reinforce the idea that allied governments are being pressured by Washington while also doubting its steadiness.
Europe appears especially unsettled. The U.S.-Europe alliance as nearing a breaking point over the Iran war, with European countries refusing to fully join the conflict and resisting efforts to turn NATO into a tool for Trump’s Middle East policy. In fact, Italy’s defense minister warned the war could jeopardize U.S. global leadership and criticized Trump’s style of decision-making, an unusually blunt sign of allied alarm from a major NATO country.
Even governments that are angry with Trump still rely heavily on the United States for military protection, economic ties, intelligence cooperation and deterrence. That dependence is especially acute in places such as South Korea and the Persian Gulf, where regional threats leave little room to simply pivot away from Washington. The trap is that allies increasingly view the U.S. as erratic, but they do not see another power center capable of replacing it.
The result is a broader strategic reckoning. Public opinion in parts of Europe is becoming more suspicious of the United States, and even some foreign right-wing leaders once ideologically aligned with Trump are putting distance between themselves and his Iran policy. At the same time, countries are searching for ways to hedge, diversify and build more autonomy without fully rupturing ties with Washington. This war is already pushing middle powers toward closer cooperation and new forms of economic and strategic self-protection. That suggests the Journal story is not just about one war or one diplomatic rupture. It is about the early shape of a world in which America is still dominant, but no longer widely trusted to lead in a predictable way.
