Over the last eight seasons, Margaret Hoover has spoken to many guests about the threat posed by Iran and what the U.S. can do about it. As the war in Iran enters a third week, we look back at how key policymakers and experts have addressed the prospect of military action against the regime.

This episode includes excerpts from interviews with Sen. Tom Cotton, retired Gen. David Petraeus, former Secretary of Defense Jim Mattis, former Secretary of State Condoleezza Rice, and more. They discuss the challenge of confronting Iran’s nuclear ambitions, the risks of pursuing regime change, and the lessons America learned from past conflicts.
