NATO Allies Refuse to Join US Naval Blockade of Iranian Ports

Apr 13, 2026

NATO allies refused to join President Donald Trump's planned naval blockade of Iranian ports, proposing instead to intervene only after fighting ends, a move likely to anger Trump who called NATO a 'paper tiger' and posted that the alliance 'wasn't there when we needed them.' NATO Secretary General Mark Rutte met with Trump on Wednesday and acknowledged Trump was 'clearly disappointed' with many allies, though Rutte signaled possible movement on opening the Strait of Hormuz. Trump is considering withdrawing from NATO in 2026 and pulling troops from countries deemed unhelpful with Iran, though a 2023 congressional provision requires approval for NATO withdrawal. Despite Trump's criticism, polling shows 70% of Americans view NATO membership favorably, with support reaching its highest levels since at least 2022, though Republican support dropped from 49% to 38% in the past year.
