Learn how America faced a critical choice after the Soviets got their own atomic bomb in this clip from The Bomb. The US had a monopoly on nuclear weapons but in 1949, the Soviets got the bomb too. In response, some urged a crash program to develop a hydrogen bomb, to stay ahead of the Soviets. Others said this was an opportunity to stop the insanity of building nuclear weapons. Facing a Soviet Union that seemed determined to expand, and political pressures to appear strong, Harry Truman chose to build the H-bomb, and so began the nuclear arms race.
