Executive summary
Over the next 30 days, if the current strike pattern persists, there is a meaningful risk of direct naval engagements between U.S. and Iranian forces in or near the Strait of Hormuz—ranging from exchanges of fire with IRGC fast boats to limited anti-ship missile launches. Each side’s efforts to assert control over the chokepoint, protect or threaten shipping, and maintain domestic credibility increases the chances of an incident that crosses prior red lines.
