Does this make me look American?

The fact that one American historian admitting something that Canadians all know to be true is news shows how truly insecure they are about their identity. Think about an American equivalent: Someone in Britain admits that the American Revolution did not advance the British agenda one bit, in fact they had to rework it afterwards. This is something I have concluded from my many semesters of American History (please correct me if your non-1776 heavy history lessons from outside New England came to a different conclusion). And from what I hear from Canadians, the fact they won the war of 1812 is similarly hammered into their heads in History lessons from an early age.

So if someone told you that a British historian admitted the above in a book, what would your reaction be?
