Following the US bombing of its nuclear sites, Iran has threatened to close the Strait of Hormuz, a critical global oil chokepoint. Rather than direct retaliation on the Iranian mainland, the US should counter this threat by seizing Kharg Island, the terminal through which 90% of Iran’s oil is exported. Additionally, the US should issue an ultimatum to Iran’s two navies—the IRGC’s coastal patrol and the regular blue-water navy to either dock and surrender or be sunk, thus ensuring freedom of navigation without a broader, destructive war on Iranian soil.
