Truman said, he'd love to help those who want to fight the Communists.
Truman preached that the United States would no longer tolerate the expansion of the Soviet Union, and they would meddle to the affairs of Turkey and Greece at the same time that it would have affects to other regions such as the Middle East to succumb into an "authoritarian" state for those who were fighting liberty.
