Final answer:
The US foreign policy during the Cold War was centered around the containment of communism, not appeasement, which is illustrated by the US's active efforts to support anti-communist factions in various international conflicts.
Step-by-step explanation:
The statement that US foreign policy centered around the idea of appeasement and not containment during the Cold War is false. The main goal of US foreign policy at that time was the containment of the spread of communism, as articulated by George F. Kennan in the Long Telegram.
This approach was distinctly different from appeasement and was aimed at preventing the Soviet Union from extending its influence beyond Eastern Europe. Containment dictated US involvement in various conflicts abroad where it supported governments or factions that were resisting communist takeovers, such as in Vietnam, Korea, and other nations during the Cold War era.
