-Depends. Certain North african nations would have nukes. South africa and Zimbabwe would have had nukes too, but only if they remained white supremacist... and given the totalitarian nationalism that seems rampant in the alternate universe thats not entirely unlikely. And having nukes makes you a target. So both those nations would have gotten a few as well as northeast africa. The Suez would have gotten nuked HARD.
Europe... Certain nations would have been obliterated. Denmark (my nation would be one of them). Historically speaking when they released the former east bloc warplans for denmark we would have been hit by 72 nukes at least. And we are a tiny nation of 5 million. We would be ghouls or dead. Most likely just dust.
Norway would make it. They have oil up the kazoo and the income generated would have ensured massive bunker systems buried in deeep bedrock. Sweden would have some bunkers. Finland too. And there would likely have been a "scandinavian commonwealth". Denmark and Finland as strategic buffers for Norway and Sweden, but with defensive capabilities and access to vault-esque bunker guaranteed in Swedish and Norwegian bedrock.
Germany would be peppered. France too. But both would have survivors. North italy would be a wasteland, and so would north spain. Schwitzerland would make it out rather well. The have historically speaking had a huge fetish for bunkers and fallout shelters so they would have alot of survivors and well... Switzerland wouldnt be a high end military target.... unless you hated chocolate and ku-ku clocks. Russia and china would have survivors... but most likely it would be people living outside of vaults who survived.
Greenland... West greenland would either have been annexed or been under de facto US controll. Thule airbase as the early warning system hub would ensure that it would be a prime target and it would likely be nothing more than radioactive bedrock after the war. Some Inuits or "Sirius" arctic ranger units might have survived... but it would be more luck than anything else.
Africa sub sahara would perhaps be the least nuked. Nothing to be gaine from nuking it.
Japan would have rearmed and gone for nukes of their own before the war, and they would have gotten nuked hard. And since most of japan is urban, not many would have survived even if some most likely did survive in vault esque bunkers.
New zealand and Australia would likely be least hit. Well... New South Wales would get it, but there is moer to Austalia than NSW. New zealand..... No military targets worth a nuke... so, no point in nuking. They would still have casulties due to weather change, radiation, fallout ect... but I dont see them as a target.
