Why did the red scare and cold war happen

The Cold War originated in the clash of systems between the United States and the Soviet Union, which is to say, a permanent confrontation of two opposed models and lifestyles: Democracy and Communism. This raised concerns in America that Communist followers might act as Soviet spies in the U.S., which started the Red Scare, named so because of the Soviet allegiance to its red flag.

for the united states of america, 1945 to 1964 was a time of high economic growth and general prosperity. it was also a time of confrontation as the capitalist united states and its allies politically opposed the soviet union and other communist countries; the cold war had begun.
