Are you quite sure? ;-) I think the USA has killed many more people. Besides, the USA controls Canada. Don't forget that. It's a fact. Canada is controlled by American corporate funding and there is not a thing that Canadian voters can do about it, I assure you.

If we, as a country, really tried to do something about it...the same thing would happen to us that happens to other people in similar circumstances where the Empire rules through its financial carrot and stick routine. Our economy would be gutted. Our political leaders would be brought down by one means or another, including assassination if necessary...and they would be replaced by loyal corporate servants of the Empire. Our medicare system would be privatized and would cease effectively to exist from that point on. Our poor would grow poorer. Our middle class would shrink.

The reason these things don't happen (much) is because we are basically compliant with Empire policy about 98% of the time, and that's good enough for the controllers. They indulge us as long as we cooperate with them.
