Explain the policy of containment forged by American diplomat George F. Kennan.

The basic idea is that communism is inefficient and will cause its own demise. Therefore, Kennan proposed that instead of engaging directly with military action, that the West should prevent its spread and allow it to collapse on its own. This reasoning is true in the sense that communism's inefficiencies were its undoing, but it also lent itself to a motivation to stop communism's spread militarily in Vietnam, Korea, China, and Eastern Europe.
