The Korean War was fought by United Nations forces, primarily from the United States, against the North Korean invaders of the South, and their Chinese allies. The Cold War was the worldwide conflict between the western democracies and Communist states, particularly the USSR. Joseph McCarthy was an obscure senator from Wisconsin until he discovered the power of unfounded accusations against supposed Communist sympathizers. The hydrogen bomb, utilizing the energy of atomic fusion rather than fission, is vastly more powerful than the bombs dropped on Japan at the end of the second World War.
