IRGC Threatens Strong Response Against Warships Transiting Strait of Hormuz

The IRGC warned it would deal severely with military vessels transiting the Strait of Hormuz, as the US Navy sent mine countermeasure vessels and destroyer escorts into the waterway. The threat came during the Islamabad talks, with the IRGC insisting Iranian sovereignty over the strait is non-negotiable. A regional intelligence official reported that IRGC forces also launched a UAV toward the US destroyers and forced at least one attempted transit to turn back.

Analysis
The IRGC threat to warships coincides with the collapse of the Islamabad talks, suggesting Tehran views Hormuz control as its primary remaining leverage. With the IRGC intelligence chief killed on April 6 and Quds Force leadership degraded, the Hormuz blockade has become the regime's most visible power projection tool, and the one area where Iran retains physical dominance despite catastrophic losses across other domains.
