Final answer:
The 'corruption of Greece' refers to a potential communist takeover. It is part of Dean Acheson's discussion about the dangers of the spread of communism (domino theory) during the Cold War.
Step-by-step explanation:
In the quote by Dean Acheson, the U.S. Secretary of State under President Harry Truman, the phrase 'corruption of Greece' is a reference to the takeover by communist forces. Acheson is discussing the potential dangers of the spread of communism during a time known as the Cold War. The 'rotten apple' metaphor he uses is an expression of the domino theory, a principle that suggests if one country falls under communist influence or control, its neighboring countries will also fall in a domino effect, due to political instability.Communist takeover, therefore, is what Acheson referred to as the 'corruption of Greece'.
