We created a weapon that could end humanity — but can we control it?
Scattered around the world, under the control of opposing nations, exists some fifteen thousand nuclear weapons. The most powerful destructive force ever created, these weapons have the capacity to devastate the entire planet several times over. When former Secretary of Defense William Perry declared he believed that the danger of a nuclear catastrophe was greater today than any time in history, his granddaughter, Lisa Perry, set out to discover why. Featuring the personal stories of presidents, cabinet members, congressmen, nuclear physicists, atomic bomb survivors, military officials, and activists, At The Brink is a primer for every world citizen to learn how we can step back from the brink.
