Last month, four Canadian soldiers in Afghanistan were killed when an American fighter pilot confused them with the other side and dropped bombs on them. To express our grief over this terrible accident and our gratitude for Canada sending soldiers to die on behalf of US interests in another hemisphere, some of America’s bravest and finest this week set fire to a Canadian flag after a hockey game while chanting “USA! USA!” If I were Canada, I would be thinking seriously about grabbing a jet and aiming at the Empire State Building right now. How did a country this unspeakably stupid get to be a superpower?
