What impact did the spread of communism have on the United state society ?

By vigorously pursuing this policy, the United States might be able to contain communism within its current borders. The policy became known as the Truman Doctrine, as the President outlined these intentions with his request for monetary aid for Greece and Turkey. The strategy of "containment" is best known as a Cold War foreign policy of the United States and its allies to prevent the spread of communism after the end of World War II.

i hope this helps :)
