On Feb. 17, 2026, Iran’s leader threatened to sink U.S. warships in the Gulf, escalating tensions during stalled nuclear talks amid military posturing.

On February 17, 2026, Iran’s Supreme Leader Ayatollah Ali Khamenei warned the U.S. that Iran could sink its warships in the Gulf, asserting the capability to inflict devastating damage despite American military deployments. The remarks, made during ongoing Geneva talks mediated by Oman, came amid heightened tensions over Iran’s nuclear program, with Iran demanding sanctions relief and rejecting U.S. calls to discuss ballistic missiles or regional influence. The U.S. has deployed two aircraft carriers near Iran, including the USS Abraham Lincoln, while Iran conducted military drills in the Strait of Hormuz, raising fears of conflict and oil supply disruptions. Despite diplomatic efforts, key differences remain, with Iran insisting on nuclear-focused talks and the U.S. pushing for broader concessions.
