I have some quibbles with this - in the War of 1812, Canada was not yet considered a nation, see your own point #14. So the war was with the British, not Canada, and the results were a wash ... "The war resolved many issues which remained from the American War of Independence but involved no boundary changes. " quoting Wikipedia

Most of the rest, like points 1, 5, 9,13, 16 ... I already knew, and think most people do!
