Actually, I'm joking. I sort of want to move to Canada. My teacher last year was Canadian. She said that there hasn't been any school violence since 1980 something and that it was only with a knife, and nobody died. Also, you're never a main political power, and so you never are the main target in most wars.....
Of course, I think the reasons I stated above are also the reason that people in the U.S. hate you. Besides, South Park is always right
