I guess we better start building a defense for the mainland of America. Everyone start stocking up weapons, ammo, water, and the beer.
I truly don't think China would ever invade America, but if we do go to war, it well probably be in Taiwan and Japan, and South Korea as though those are close military bases in the region of China.
If Russia went to war with China, China would just kick Russias but in my opinion, that is on the ground war. The air war Russia would win, but on the ground, Russia still throws in poorly trained troops into conflict while the better ones stay back watching thousands of noobies come back with bandages all over them.
For a while I thought our next war would be with North Korea, but there to chicken to get there butt kicked right now. I really believe that there well be a war in Iran. I have also heard somewhere that the younger people in Iran actually like America more than their country, as in education, women rights, and more.
