Let's say that WWIII starts when China and Pakistan invade India for whatever reason (propaganda war, escalated border crisis, etc.) and at the same time North Korea attacks South Korea without Chinese knowledge bringing the United States into the war. After a few years China invades Siberia and Southeast Asia for resources provoking Russia and Australia with the rest of the British Commonwealth. During the war the Russian front becomes comparable to Stalingrad if not worse. Eventually China, Pakistan, and North Korea are capitulated with the nations mentioned along with Taiwan, South Korea, and Japan (Which China invaded to prevent a spot for the US to invade from before being taken back) almost completely destroyed.
How would the US, India, UK, Australia, and a very Angry Russia deal with the defeated nations to make sure China doesn't start a second war out of revenge as Germany did in WWII?
For the sake of the scenario we'll assume that either nuclear weapons don't exist or that cooler heads prevailed before mutual assured destruction ends the whole discussion.
