It's now been 75 years since the nuclear attacks against Hiroshima and Nagasaki ushered in the beginning of the atomic age, but the threat of nuclear devastation is still very much with us. Our guests this week warn, though, that it’s not a sudden surprise attack that we should be most worried about, but instead, a sudden surprise mistake. 

Former Secretary of Defense William Perry and the Ploughshares Fund's Tom Collina join us to lay out that that warning and discuss their new book, “The Button: The New Nuclear Arms Race and Presidential Power from Truman to Trump." 

Guests: 

• William Perry, a former secretary of defense and a professor of international relations at Stanford University
• Tom Collina, the policy director for the San Francisco-based Ploughshares Fund

Host: Keith Menconi
