So, after reading through this thread I'm inclined to agree with Patroklos et al. But, I want to play devil's advocate and offer a war plan for the rest of the world.
The main goal will be to cut off the US and China from resources, oil in particular, and force them to sue for peace. I don't see any reasonable scenario where the rest of the world could actually invade and occupy the US and/or China.
In Canada, Mexico, and South America, guerrila warfare would be the primary tactic. Tie up as much of the US army as possibly by retreating to remote locations (northern canada, or the mountains of south america). Blow up oil refineries, if necessary, to prevent them from being captured by the US. Terrorist attacks inside the US would also be effective, especially targeting US oil refineries in Texas and the gulf of Mexico. Latin America would also work to spread propaganda among Latinos inside the USA. A wide spread race riot could shut down the economy of Texas, California, and the southwest, and possibly even cause some US military to defect.
Some strategic retreats would be necessary. Rebase the air force of Canada to Europe. Rebase the air forces of Japan, Taiwan, and Australia into the Korean peninsula. Most likely, after that, Japan and Australia would be of no further aid, but that's OK. They will focus simply on keeping the US navy busy.
Use these combined air forces, combined with the entire ground force of North Korea, to drive into China as fast as possible. The USA would probably only have carrier-based aircraft ready to react, which would be outnumbered badly, and Chinas would be badly out-teched by South Korea, Australia and Japan. The focus of these battles would not be on gaining territory, but simply to maintain a flow of resources from Russia into this area, and to disrupt transportation inside China as much as possible. In particular, try to disrupt the flow of food from the interior of China, to the coast where most of the population is located. If the Chinese government is unable to feed it's citizens, or even it's military, it will quickly collapse.
I'm going to ignore Africa, since I can't imagine them doing anything in such a conflict. If anything, this would help the USA since we wouldn't have to send them foreign aid
Europe would focus all it's efforts on maintaining control of the middle east, and destroying any location from which the USA is drawing resources. England would be a big liability, since it imports almost all of it's food, but there are ways around this problem. Probably some ground forces can be diverted to help the fight against China. All production will be focused on navy, air, and AA and simply denying the USA the use of strategic resources.
If the USA is denied ANY foreign oil, as well as other resources, and the Chinese government collapses, the USA would eventually be forced to give up.
