An End to the Carter Doctrine? - What it would Mean if US Left the War While the Strait is Still Shut?

Gregory Brew of Eurasia Group joins Rory to discuss the potential collapse of the Carter Doctrine following a provocative social media post by President Trump regarding the security of the Persian Gulf. The discussion centers on the 1980 policy that committed the U.S. to using military force to protect the flow of oil, a guarantee that now appears to be evaporating as Trump signals an end to U.S. protection for global energy routes. With the Strait of Hormuz closed for over a month and oil prices soaring toward $200, the episode explores the "Unilateral Taco" scenario where Trump might abruptly end hostilities regardless of whether the waterway is reopened. Brew analyzes Iran's shift from a struggle for survival to a strategic effort to maximize gains and impose tolls, leveraging their functional control over the world's most critical maritime chokepoint. The conversation also breaks down the "hydraulic relationship" between energy prices and political pressure, specifically how Iran uses allies like the Houthis as a lever to keep prices high and force a U.S. de-escalation. Brew examines the precarious position of GCC nations and Israel, who face the risk of their territories becoming permanent "live fire zones" if the U.S. abandons its traditional security role. Finally, the episode questions what a post-war status quo looks like and whether the credibility of U.S. energy guarantees can ever be restored after such a fundamental shift in geopolitical priorities
