Well, according to the wiki's lore, there was an event known as the resource war with the middle east, which culminated with a short nuclear exchange prior to the war which raised fear of nuclear weapons. Since Europe depended on Fossil Fuels, when America invented sustainable fission power it bankrupted a large part of Europe and made the war they had waged near utterly useless. Many European nations were dropped into civil war over the remaining eonomic interests which were (???) and that went on until the Great War, though I don't think this is fully confirmed canon.
After the Great War, it doesn't say. It doesn't say which European nations used nuclear weapons during the war, so who knows, maybe they weren't as badly damaged as the US or China? Though they were still involved so I dunno.
I don't know if a European Fallout would sell as well. Society in the Fallout universe was very introverted, so Fallout in England or France wouldn't have very many of the same items or brands like nuka cola and such. I don't know if it would be as fun...
What do you mean evil laugh!? This is how I always laugh!
