Truman Doctrine: Questions

Do you agree with the statements and policies outlined in "the Truman Doctrine?" Does the U.S. have an obligation to aid foreign countries? What would your [insert your name here] Doctrine say?
Truman does a lot of switching between facts, rhetoric, numbers, and metaphors. What are some examples where this is particularly effective? Why take such an approach?
Who would you pick to play Truman in a movie and give this speech?
Fun fact—over half of the men Truman was speaking to were Republicans and, for the most part, couldn't stand his Democratic-party guts. (Just as they do today, both parties clashed over money and government spending, and here was Truman requesting to send millions of dollars to a foreign country.) What do you think was going through his mind when he spoke? What would have been going through your mind if you were the President?
What if the Truman Doctrine had been a big failure and had not become a major policy of the U.S.? Do you think this sort of policy was inevitable? How might the Cold War have played out differently?
