Iran says the Strait of Hormuz stays closed until the U.S. meets its terms

# Why This Matters Iran's threat to close the Strait of Hormuz represents a direct challenge to global energy security and poses immediate economic consequences for oil-dependent nations worldwide. Approximately 21 percent of globally traded petroleum passes through this vital waterway, meaning a sustained closure would trigger severe supply shocks, driving oil prices sharply higher and potentially tipping vulnerable economies into recession. The invocation of the "Islamabad Memorandum"—a framework Iran has referenced in previous disputes—signals an attempt to internationalize its demands beyond bilateral U.S.-Iran relations, potentially drawing Pakistan and other regional actors into the dispute. For the U.S. and its allies, this escalation forces a choice between negotiating under duress or risking a military confrontation that could disrupt shipping, destabilize the region, and further entrench the cycle of sanctions and counter-threats that has defined Iranian-American relations for decades.
