A first-rate history of how the Cold War was conducted. As World War II ended, the two former allies immediately began to look upon each other with suspicion. Many events converged that pushed the U.S. and the USSR apart. Truman had little patience with Russia; he did not understand the effect of the terrible losses the Soviets had incurred during the War. (For every American killed, there were 27 Russian deaths—almost 12 million.) In any case, Stalin was a paranoid maniac. What Sheehan has done is to concentrate on one aspect of containment: building the anti-ballistic missile shield as a defense against the Soviet bomb. He focuses on some of the brilliant characters involved in the decision to build and man missiles, such as the lead scientists, Johnny Von Neuman, a Hungarian refugee, fiercely anti-Soviet and a brilliant physicist; and Werner von Braun, a completely amoral, former rocket-builder for Hitler. The center of the book is Bernard Schriever, who immigrated from Germany as a child, became a brilliant golfer, and a flier in the Air Force. This thoroughly decent man, a protégé of Hap Arnold, fought Curtis LeMay to build a defense rather than bank on an offensive program.
