The division of Europe following World War II, and the ideological differences between capitalism and communism which alienated former allies, initiated the Cold War. The Truman Doctrine, the Marshall Plan, and the Berlin Blockade created even greater distrust between the communist bloc and the USA and its allies. A communist victory in China and the subsequent Korean War moved the focus of the Cold War to Asia, and with it the fear of the domino effect. Added to these conflicts were the Space and Arms Races, as the superpowers vied for nuclear supremacy. The nuclear deterrent prevented open conflict, although each side exerted influence worldwide. When the Berlin Wall was erected in 1961, it seemed the threat of a world war would remain.
