This is a question that leads into another question that leads into another question ... and then even more questions. My advice would be to break it down into the distinct questions.
As the United States entered World War I, Woodrow Wilson proclaimed that "The world must be made safe for democracy."
Question #1: To what extent did the United States, itself, live up to this ideal both during the conflict?
Question #2: To what extent did the United States, itself, live up to this ideal immediately after the conflict?
Question #3: Finally [ha!], do you believe in curbing civil liberties during a time of war?
Question #4: Is this an issue [curbing civil liberties during a time of war] that only conservatives believe in?
Question #5: In historic terms, can the United States justify its treatment of dissenting minority groups?
[I assume this means "during a time of war."]
Once you have broken it down into five separate questions, you can see that the questions are not just related, but actually build upon one another. This is a "work smarter not harder" approach, as answering them in order allows you to develop answers based on historical evidence you have used to make your previous argument(s).
