Europeans are increasingly questioning whether the United States would come to their defense in a military crisis, according to a new survey showing confidence in America's security commitment has fallen to record lows.

The poll, released Wednesday by the European Council on Foreign Relations (ECFR), found that only 11% of respondents across 15 European countries now view the United States as an ally "sharing our interests and values," down from 22% in November 2024.

Researchers said the findings reflect "deep European distrust in the U.S." ahead of upcoming G7 and NATO summits.

While most Europeans still see America as a "necessary partner," majorities in every country surveyed said they no longer believe the U.S. would necessarily come to their aid if they were attacked.

The survey comes as European leaders push for greater military independence amid concerns about Washington's long-term reliability.

According to the report, President Donald Trump's pressure on NATO allies, criticism of the alliance, plans to reduce U.S. troop deployments in Europe, and other foreign-policy disputes have accelerated calls for Europe to strengthen its own defenses.

"Across the continent, there’s clear support for reducing dependence on Washington," ECFR senior policy fellow Jana Kobzová, who co-authored the report, told The Guardian. "Europeans are increasingly open to higher defense spending and, crucially, show a striking degree of confidence that neighboring countries would come to their aid in a crisis."

Co-author Paweł Zerka said growing support for self-reliance has "created a window for Europe’s leaders to go further and faster" on security.

Most respondents said they have more faith in assistance from neighboring European countries than from the United States in the event of a conflict.

Support for increased defense spending has risen across much of Europe, while nearly half of those surveyed favor joint European Union borrowing to finance military investments. Large majorities in several countries also support reducing dependence on U.S.-made military equipment and buying more European-produced defense systems.

At the same time, Europeans remain reluctant to pay for military expansion through cuts to domestic spending, while support for replacing NATO with an EU-only defense alliance remains low.

Despite current frustrations, many Europeans believe relations with Washington will eventually recover. In nearly every country surveyed, the dominant view was that U.S.-European ties would "probably get better" after Trump leaves office.

The survey also found continued resistance in parts of Europe to Ukraine joining the European Union, with respondents in several countries more likely to oppose Kyiv's membership bid "in the current context" than support it.

The poll was conducted in May and surveyed 19,481 respondents across 15 European countries, including Austria, Bulgaria, Denmark, Estonia, France, Germany, Hungary, Italy, the Netherlands, Poland, Portugal, Spain, Sweden, Switzerland, and the United Kingdom. The margin of error ranged from 2.21 to 4.46 depending on the country.
