I think that we are more likely to go to War with China for other reasons really. China is amassing a HUGE army. Maybe the largest anyone has ever had. If they get too ambitious, they will try to take Tiawan and maybe some other nations around them. I seriosly doubt that Russian and China will ever fight together against the US. Maybe, just maybe if China and North Korea worked things out, they could be alies, but I kinda doubt Russia. Also, if the scenario Lord Piot presented happens, it will easily be world war 3, in which case Canada will be allied with the US and Great Britain. Sorry man, you are not safe up there in Canada...your more of a buffer to the north than anything, ally or not.
