Answer: question 6 is “c” to defend member nations against Soviet expansion and aggression.
Question 7 is a little more difficult because while America did want to spread democratic values, they also wanted a bulwark against Soviet expansion. I would probably say “d” in this case.
Explanation: The Soviets had already moved into Asia at the end of WWII, taking several of Japans processions, which included parts of N. Korea and Japanese islands. They had joined the war against Japan, answering a request from the US for assistance. It was important that the US not abandon Japan after WWII since there’s a good chance the Soviets would’ve moved in just as they did in parts of Asia and East Europe.
