Passage of the McCarran Act was related to which of these?

Question

1-Vietnam War
2-Marshall Plan
3-Truman Doctrine

I think it's the 3nd option. Is it right?

Answer 1

I bet if you do a google search of the McCarran Act, you will find the answer very quickly.

Answer 2

Yes, and no. The act was passed in 1950, during Mr. Truman's term in office, over his veto. The Truman Doctrine had to do with containing communism overseas to nations already under Soviet control. The McCarran Act was to "battle" "subversives" at home in the USA during hysteria over supposed "communists" working in the federal government, in the arts, and elsewhere in the United States.
