Having flown for an American Airline for the past 15 or so years, I can certainly agree that some American's are arrogant and brash. God knows I have seen my fair share of of self centred, pompous asses, whose cockpit management skills rival those of 5 year olds as they fight over the last lollipop.......childish and immature at best.....yes.....some certainly need a swift kick in the ass.
However, having been amongst them during 911, I can tell you they were profoundly affected by this event, and they will carry those wounds with them for many lifetimes.........many now preach an isolationist approach......let's hope this doesn't happen.........again, as I said, they did NOT deserve 911.....
Also, a quick read of the history books will show if it was not for the American Industrial machine supplying the UK AND The Soviet Union in WW2, as well as committing their military into the war, the war in Europe would have been lost......those facts are indisputable....
