European confidence in US alliance plummets to historic low of 11%, survey shows

Jun 10, 2026

A survey by the European Council on Foreign Relations reveals European confidence in the U.S. has plummeted, with only 11% now viewing it as an ally—a historic low. This is attributed to President Trump's policies, leading majorities to doubt U.S. security guarantees. Consequently, support is rising for increased European defense spending and reduced reliance on U.S. military hardware.
