I want to know the answer to the following question:
What did the US not want to see repeated?
All the background I'm provided with is that "However, President Truman later acknowledged that he believed fighting the invasion was essential to the American goal of the global containment of communism as outlined in the National Security Council Report 68 (NSC-68) (declassified in 1975):". Is that enough to answer the question?
Answer: no
