Could Donald Trump order a strike that eliminates Iran’s supreme leader, Ayatollah Ali Khamenei? With tensions between Washington and Tehran escalating and protests sweeping Iran, with thousands now killed, the idea of dramatic military action has moved from the fringes into serious debate.

A key figure in U.S. diplomacy on Tehran and a veteran negotiator of the 2015 nuclear deal, Malley brings deep insight into the limits of force, the power of diplomacy, and how U.S. policymakers think about confronting Iran’s leadership.
