Before ESTA you had these landing cards which contained similar questions. One that stood out for me was, "Are you, or have you ever, been part of the Nazi German regime", or words to that effect. Surely being a Nazi is a requirement for settling in the USA now, what with good people on both sides..?
UK asks the same questions (or at least they did a couple of years back when I got my citizenship) They also ask the war crimes/genocide/terrorism questions mentioned above. Guess it's their response to at some point finding someone who did those things who just turned around and said "Well, you never asked!".
