@Yuri, that's ridiculous, N. Korea has no power at all. I expect China and Russia to get along well (brought together by common enemy) and lead the other side, against US/Israel. Neither is very expansionist. They're just going to want to control countries on their borders and re-establish their traditional spheres of influence. Places like Tibet, Taiwan, Korea etc will be solidly in China's sphere. Ukraine, Poland, and (in general) former USSR nations had better get along with Russia. Japan (and S. Korea) will be a bone of contention with China, and Western Europe, with Russia. These places are currently in US camp (the so-called free world) and will have to decide which way to go. But if WWIII starts, it will start in the Middle East.
Australia is in a great out-of-the-way position "down under", but sooner or later it too will have to choose between the "free world" and China. Get used to the idea of a "yellow invasion". Long-term you can't stop it, just make sure it's peaceful.
You've seen how US behaves for decades now. You've heaped scorn on them. You seem to expect Trump to start WWIII with some random twitter message. No, US will be stable for quite a while. But given recent history, how you can calmly expect it to go away quietly is beyond me. Just a short while ago they were viciously slaughtering Europeans, and confronting Russia with nuclear holocaust. Not to mention Japan, Vietnam etc. And surely you can see the long-term plans for the Middle East.
If you disagree, fine, maybe you're right. But simply getting my point across seems hopeless. Fortunately Putin and Xi Jinping are different: not dummies. No doubt they're well aware how situation is developing.
@anunitu, you're right US should get out of Afghanistan and hope Putin is dumb enough to get back in. But neither is likely. I'm disappointed to see Trump getting in deeper but even if he were sensible, future US presidents won't be.
