The world should evolve into Spheres of influence. The two great powers will remain China and the US. You can virtually draw a diagonal line across the world map.

However, subpower should resume. Israel should control the historical Levant, regardless of historical powers. Saudi should be allowed to take control, ultimately, of its Arab brother states, including north Africa, except Egypt, which should be resolved into Europe, which should utilize ancient control of its borders.

Russia will be given control of itself and the Caucasus, including some of its normal terrain, excluding European terrain, but will remain in the Chinese territories of influence.

Central Africa will go as it will, but South Africa will remain American, along with its allies of the region.

Brazil and Argentina will remain in Chinese territories, but the rest of South America and Central America, will be US territory.

The rest of North America belongs to the US, including Canada and Greenland, though Greenland control can continue to consider itself European.
