where it already existed? true or false?

The statement is true. The US turned to a policy of "containment" with respect to keeping communism only  where it already existed.

Explanation:

The Containment Policy was the foreign policy strategy of the United States adopted in the early years of the Cold War with which it tried to stem the so-called Domino Effect, determined by a progressive shift of countries that, on a regional scale, transited politically towards forms of Soviet communism, rather than towards western European capitalism and liberal democracy, typical of the western countries supported by Washington. Among the main supporters of containment was diplomat George Frost Kennan.

Based on the principle that isolation leads to stagnation, the US wanted to isolate the Soviet Union and its satellite states economically and politically. The policy led President Harry S. Truman to introduce the Truman Doctrine in 1947, thus leading to American involvement in both the Korean War and the Vietnam War.
