The Cold War was conflict between two ideologies: Democracy versus Communism. When World War II ended, there was now a power struggle between the U.S. and the U.S.S.R. Both built alliances with other countries in a bit to support their ideals. They provided their allies with financial and military support to ensure that their interests were protected. Many countries were devastated during this period and it was only during the dismantling of the Communist regime did the Cold War come to an end.
