Arms Race

The U.S. wanted to be superior to the Soviet Union. Scientists developed a bomb more powerful than an atomic bomb. They created the H-bomb (hydrogen bomb), which has the fore of 1 million tons of TNT. J. Robert Oppenheimer was the leader of the bomb team. Truman authorized the H-bob creation because of political pressure. Less than a year after the Americans blasted the H-bomb, the Soviet Union exploded their own. This started tension between the two superpowers, the U.S. and the Soviet Union.
