I'm American (and travel to Canada a lot). Why exactly would Canada WANT to join the U.S.???? I can see why some americans would want to "annex" them, but thats a whole other issue. To "annex" them makes them US (not U.S., but US). No one has really, rationally discussed the United States and Canada joining to create a NEW place that has some of each. in theory the best of each. The discussion in the U.S. is always to ADD canada to US. Meaning more U.S., not a "different" U.S.....

Run Canada, Run.

A devils advocate question: why is it never the idea to annex the U.S. into Canada????
