The main purpose for the Truman Doctrine was to prevent Soviet expansion
during the war, mainly expansion into other European countries such as
Greece and Turkey.
The correct answer is A) to contain Soviet expansion.
The Truman Doctrine revolved around the idea of containment. This was the American federal governments goal of stopping the spread of communism into other countries. This is why the US tried to contain Soviet expansion, as the Soviet Union was trying to implement a communist system in several different nations. To combat this, Truman will end up giving $400 million to countries like Greece and Turkey who are in jeopardy of following under control of the Soviet Union.
