NATO allies reject Trump's plan to blockade Iran's Strait of Hormuz

NATO members including Britain and France announced on April 13 they will not participate in U.S. President Donald Trump's military blockade of the Strait of Hormuz, which began the same day following failed weekend negotiations to end a six-week conflict with Iran. The allies said they prefer diplomatic solutions and want to keep the vital shipping lane open, through which one-fifth of global oil typically passes and which Iran has effectively closed since the conflict began on February 28.

U.S. Position

Trump administration views allied participation as essential to the blockade's success and has pressured NATO members to contribute military support. Trump stated on April 12 that the blockade would begin and that other countries would be involved, and has threatened consequences for NATO if members do not provide concrete commitments to help secure the strait.

European and Allied Position

NATO allies including Britain, France, and Germany argue they were not consulted before the U.S.-Israeli operation against Iran began and reject being drawn into what they characterize as an American conflict. British Prime Minister Keir Starmer stated clearly that "we're not getting dragged into the war," while Germany emphasized that NATO is a defensive alliance, not a tool for foreign intervention. These countries prioritize reopening the waterway through diplomacy rather than military blockade.

  • The Strait of Hormuz spans just 21 miles at its narrowest, making it highly vulnerable to naval disruptions.
  • NATO's Article 5 has been invoked only once, after 9/11 attacks on the U.S.
  • IRGC Navy pioneered swarming tactics with speedboats during 1980s Tanker War.

US-Iran Ceasefire War

The United States launched military strikes against Iran on June 26, 2026, in response to a drone attack on a commercial cargo ship in the Strait of Hormuz, calling it a "foolish violation" of the 60-day ceasefire agreement signed just days earlier[2][4][14].
