By in-depth history of how the nuclear peace was won by complementing deterrence with reassurance, and then jeopardized by discarding arms control after the Cold War ended. Tells the story of high-wire acts of diplomacy, close calls, dogged persistence, and extraordinary success. Brings to life the pitched battles between arms controllers and advocates of nuclear deterrence, the ironic twists and unexpected outcomes from Truman to Trump.

New guardrails have to be erected. Read more.
