During the Cold War, what was the main concern of the United States?

During the Cold War, the main concern of the United States was the containment of communism and the spread of Soviet influence. The United States and the Soviet Union emerged as two superpowers with opposing political and economic systems, leading to a period of heightened tensions and ideological rivalry. The United States feared the expansion of communism and Soviet influence, particularly through the Soviet Union's support for communist movements and governments in various regions around the world. The policy of containment, developed by the United States, aimed to prevent the further spread of communism and Soviet influence by supporting friendly governments, providing military assistance, and engaging in diplomatic efforts to counter Soviet actions. The United States was deeply invested in safeguarding its interests and promoting democracy, capitalism, and Western values as an alternative to communism during the Cold War.
