This one is an effort at creating a world map for the rather sketchily described pre-nuclear-war setting of the Fallout game series. Fallout is something of an AtomicPunk world, with technology more like an upgraded 1950s than anything logically following from our world: the USSR is still around in 2076, although it is no longer the principal enemy of the US, having fallen behind China both economically and technologically. China, which has modernized while remaining a dictatorship, is the primary Evil Empire. (Indeed, US-Soviet relations are relatively cordial nowadays)
The US is rather different, having been reorganized for supposed efficiency into a number of confederations occupying an intermediary political level between state and federal. With the increasing economic and environmental crises of the 21st century, the US has become increasingly dictatorial, and has occupied both unstable Mexico and, more recently, uncooperative Canada to gain better control of their resources.
It's a bit of a messed up world: the last of the oil is running out, global-warming related desertification is increasing, and nuclear power is apparently more difficult to control and prone to disastrous failure modes than in our world. A form of fusion power cell has been build, but it is still so expensive to built in large sizes that it has not yet made a serious dent in the power shortage. A united Europe went to war for cheaper oil in the 60s against an Arab coalition: after a horrible bloodbath, the middle East was a wreck and there was no oil to have: bitter recriminations and eventually civil war followed. Tel Aviv was nuked and the Israelis did not respond very forgivingly.
Now, China and the US are fighting over the last scraps of oil in Alaska and the oil pipeline: The US has launched a counterattack on the Chinese mainland, and the Chinese fear the Americans will join up with their (largely kept secret from the outside world) internal rebellions....the world is on the brink of nuclear catastrophe.
