Okay, but once again, we're blaming England this time, for Nazis being Nazis. Am I the only one who sees a little hypocracy in America saying "Why didn't somebody do something, and stop them?" When they didn't get involved until after they already took over Europe, and their allies attacked Hawaii. After a year of London being bombed constantly, because all of our World War II scenarios involved us going to war with Briton.
I'm sure Chamberlain should have stopped them. Or maybe France. Since historically, they've always been able to do that before, without our belated help.
When it's people who stand around, and say "Why don't people do something" until it's far too late, it's called the Bystander Effect. Hindsight is 20/20.
