This weapon [the atomic bomb] has added an additional responsibility - or, better, an additional incentive - to find a sound basis for lasting peace. It provides an overwhelming inducement for the avoidance of war. It emphasizes the crisis we face in international matters and strengthens the conviction that adequate safeguards for peace must be found.

Leslie Groves
