Answer:
The Cold War was a diplomatic, ideological and at times military conflict that confronted two well differentiated sides: the Western or Democratic Bloc, led by the United States; and the Eastern or Communist Bloc, led by the Soviet Union.
In this context, the European countries were divided into these blocks, drawing an imaginary Iron Curtain that divided Western and Eastern Europe: on the Eastern side were the countries with communist totalitarian regimes, under the orbit of the Soviet Union; while in Western Europe they were free, democratic and capitalist nations organized around NATO.
In general, the least developed European countries, as well as those on the American continent, had internal conflicts in which communist movements attempted to overthrow legitimate governments, leading to the formation of guerrillas and the development of even civil wars.
In some cases, such as the notorious case of Cuba, these communist movements managed to seize power and thus establish left-wing dictatorships, but in most cases, these movements were suppressed and freedom was guaranteed.
