arms race(tension#4)

The nuclear arms race was central to the cold war. Many feared where the Cold War was going with the belief that the more nuclear weapons you had, the more powerful you were. Both america and russia massively built up their stockpiles of nuclear weapons.
The world greatly changed when USA exploded the H-bomb in 1952. This one bomb was smaller in size than the Hiroshima atomic bomb but 2500 times more powerful. The Russians produced an H-bomb in 1953 and the world became a much more dangerous place.
However, it is possible that the sheer power of these weapons and the fear that they evoked, may have stopped a nuclear war.
