I'm not an expert in history but that 1st panel seems unlikely. Cute though

If I recall correctly, it was initially the French and the Native Americans that made up the population of the northern and western frontiers, then Brittan kicked their collective asses out of the Ohio river valley, then they pissed off their own colonists who then, with the help of the French, kicked them out of New England and went on to form the US of A, then Napoleon decided he'd rather have Russia rather than N. America (since the continental bonus is bigger) so he sold off France's claim to anything on the continent to the US, then Brittan said "fuck you" tried to come back and take over and got their asses kicked a second time, and those who didn't want to go crawling back to their king decided to hang out past the 49th parallel with the French and the Native Americans and formed Canada.
So yeah, everything but the first panel is pretty much correct.
