Much like the hatred of a teenager for his parents.
Having kept up with politics for 20+ years, I DO know about the truth of the above statement. The absorption of any province of Canada would be a liability for both nations. The best thing for the western provinces is to form an independent nation, and then decide whatever relationship they wanted to have with the remainder of Canada and the USA. The US has all the territory we will ever need. And since this would not be unanimous in the provinces, we would have malcontents to deal with. Let Canada do whatever they want to, but the best thing for the US is to ignore Canada and her problems. The less we have to do with that nation, the better off the US will be. They have nothing to add to our great country, or otherwise they would have already added it to theirs.....
