Is THIS the Real Reason Weather is Getting Wilder?

4. Okay, this may be off point, but it came to me while watching this video.

If DU wants to delete I am fine with it. I am writing this because I think that eventually, climate change will really mess up this planet. What I am wondering is the U.S. and Canada are staunch allies. What happens if climate change destroys U.S. agriculture enough so people are starving, and helps Canada's agriculture so it doesn't have to import agricultural products but not enough to export to the U.S. The U.S. has problems importing from other countries. Would the U.S. invade Canada? The reason I am asking is I don't think countries have real friends. They have allies because it is beneficial and enemies because the other countries have what they need and can't get it from them. What the country does is examine the pros and cons of invading the other country. I believe that most countries are amoral when it comes to other countries and also certain people in their country. So if DU does not delete my post I would really like people to respond positively or negatively.
