After the allied surrender, relations between the USSR, Japan, and Germany went steadily downhill. The first strike came from the USSR, in 2001. From a satellite, they obtained the positions of all German nuclear launch pads and attacked them. Germany, only able to get off some missiles before its launch system was hit, collapsed. Europe was a nuclear wasteland.
Asia, too, was widely hit, during the second Russo-Japanese war. It finally ended in 2009. Only Africa had not been hit, but that collapsed into anarchy. Argentina, Brasil, and South Africa were the last stable nations on Earth, but during the 2011 war to end Apartheid, South Africa was wiped out by a secret cache of American missiles that was discovered in Cuba. Most of South America, except for the nuked regions of Colombia, which had been controlled by Germany, was part of either Brasil or Argentina,
With the estimated human population of the Earth down to around 500 million, Argentina and Brazil agreed to unify after the South African war. Meanwhile, across the globe, new civillizations have started to emerge- a rump state near where New York once was, a city state in the Congo- forseeing that humanity might return once again, to conquer the Earth.
They have a long way to go.
