Answer:
The correct answer is B. The United States and the Soviet Union became enemies after World War II because they each wanted to promote their competing political ideologies.
Explanation:
The Cold War was a political, economic, social, military, informative and scientific confrontation initiated after the end of World War II between the Democratic Western bloc led by the United States, and the Communist Eastern bloc led by the Soviet Union.
The reasons for this confrontation were essentially ideological and political. On the one hand, the Soviet Union financed and supported revolutions, guerrillas and socialist governments, while the United States gave open support and propagated destabilizations and coups, especially in Latin America and Africa. In both cases, human rights were seriously violated.
Although these confrontations did not lead to a world war, the seriousness of the economic, political and ideological conflicts marked a significant part of the history of the second half of the 20th century. The two superpowers certainly wished to implant their model of government throughout the planet.
