The U.S. and Israel just fought a second war over Iran's nuclear program—and one of the world's leading nuclear experts says America lost. Iran's uranium stockpile sits fully intact in tunnels too deep to reach, and Tehran walked away with more leverage in nuclear talks.

James Acton, a physicist and longtime analyst of Iran’s program, joins host Jon Bateman on The World Unpacked to give a detailed update on this crisis. Has the new supreme leader already decided to build a weapon? How quickly could Iran “break out” or “sneak out” to the bomb? And why does Acton now expect more wars—followed by a nuclear detonation?
