One of the questions asked in that study was, How many Vietnamese casualties would you estimate that there were during the Vietnam war? The average response on the part of Americans today is about 100,000. The official figure is about two million. The actual figure is probably three to four million. The people who conducted the study raised an appropriate question: What would we think about German political culture if, when you asked people today how many Jews died in the Holocaust, they estimated about 300,000? What would that tell us about German political culture?
