Clear the way—America is about to dig one of the most ambitious engineering projects in human history, all while rewriting the fine print of hemispheric diplomacy. In this episode, we follow the epic (and occasionally eyebrow-raising) story behind the Panama Canal: disease-fighting doctors, unstoppable steam shovels, and a president who treated foreign policy like a personal side quest. And then there's the Roosevelt Corollary, which boldly announces that the U.S. is now the Western Hemisphere's self-appointed problem-solver—whether Latin America agrees or not. It's mud, malaria, geopolitics, and one very determined Teddy Roosevelt.
