19. Critical Thinking #4 Read pp. 550 – 564 in your textbook. Imagine you are the U.S. President in the years before the Japanese attack on Pearl Harbor. How would you convince isolationists that U.S. entry into WWII is necessary? Write a 2 paragraph response that uses specific historical examples to support your stance. (Hint: think about the relationship between war and the U.S. economy, the future of democracy, German military aggression, etc.)

20. Critical Thinking #4 Due Thursday, February 24: Read pp. 553 -558 in your textbook Imagine you are the president of the United States just before the Japanese attack on Pearl Harbor.

How would you convince those with differing opinions that your plan is the best course of action? Use specific historical examples to support your stance (assume that you don’t know about the atrocities of the Holocaust)
