The Strait of Hormuz Could Close: Admiral Stavridis Warns What Comes Next in the Iran War

As tensions escalate in the Middle East, one of the world’s most critical energy chokepoints is back in the spotlight: the Strait of Hormuz. In this episode of State Secrets, Cipher Brief CEO Suzanne Kelly speaks with Admiral (Ret) James Stavridis, former Supreme Allied Commander of NATO, about the growing risk of escalation with Iran and what it could mean for global security. Stavridis explains why the narrow shipping lane that carries roughly 20% of the world’s oil and 25% of global natural gas could quickly become a flashpoint if Iran attempts to mine the waters or disrupt tanker traffic. With thousands of potential naval mines, limited mine-clearing capability in the region, and rising oil prices already impacting the global economy, the stakes are enormous. The conversation goes beyond the Gulf — examining how China and Russia are watching the conflict, whether the U.S. could find an off-ramp to avoid a prolonged war, and what emerging threats could come next. From cyber-attacks and terrorism to great-power competition at sea, Stavridis lays out the strategic landscape leaders are navigating right now. If the Strait of Hormuz closes, even temporarily, the economic and geopolitical consequences could ripple across the globe.
