Worse shithole than US. Probably nuked. Also, because of resource wars, has no resources whatsoever to fuel even pre-industrial economy.
You also get Tenpenny in Fallout 3 mentioning that he escaped from there. Not sure if anyone in Fallout 4 mentions anything (i think there is someone). In Fallout 76 you have that one ghoul who made it across the pond BEFORE the war because things were already shit.
I mean, Britain now is in dire straights - next to no domestic production, elites mooching off money laundering, tax evasion, and finance + services sector (which doesnt help one bit with development of the nation/country). Ireland is even worse.

Resource wars. Some terrorists detonated a nuke in Tel-Aviv, so there was a limited nuke exchange between Israel and arabs. Then more of the same - nukes flying everywhere. It is pu to the debate regarding Soviets - US and them were not excatly enemies, so Europe might've been in soviet sphere of influence. Thus you can assume that it was Europe vs Soviets. And they nuked each other too. Maybe Siberia as a region kinda survived, but knowing that soviets would put some nasty labs there, its a frozen hellscape full of monsters and anthrax.

Mad Max.
>Japan/asia
Became chinese slaves. Then got nuked.
Contrary to the wide belief, china is not a glowing crater that you can see from space - that is just a very very bad sun glare. It is a nuked wasteland though.
Most likely than not, only US post-war has enough resources to rebuild. Everything else is just a wasteland.
>Africa
>Southern Americas
Nothing changed for them. They are just wastelands (due to climate change induced by nuclear war and radiation).
