Er..no, unlikely, plus this isn't an RP so I'm a little puzzled about you typing in first person.
The UK's emergency government plans were strong enough that we would stay together as one nation and slowly recover, as I have outlined above.
My own TL is planned to go into the post-war period in the eplilogue (when I get around to writing it.
).
From a personal perspective my whole family in the UK have dual nationality and Swiss passports since the late 1970s. Had a situation like the 1984 war developed with the fairly lengthy lead up time my parents could well have decidesd Switzerland would have been a far safer place than the UK since everyone would have realised that if the balloon went up nuclear war was all but inevitable. o answer the question I assumed that was the deciosion they made and the family survived the war which, had we stayed in the UK, we might well not have done.
Switzerland was better prepared tha most in civil defence preparations during the early 1980s. People sometimes had their own fallout shelters I I remember seeing one owned by one of my Swiss relatives at the time (it doubklled as a rather well stocked wine cellar) Apparently the Swiss government had large official shelters in the Alps and elsewhere that might have beebn used by thr government and the public.
Arugably this would have meant that Switzerland would have been better able to survive as a national entity particularly if, a a neutral, it was not directly attacked. There would have been a large amount of fallout from the 1984 war from the attacks in Germany and to an extent France and Italy. I assumed the Swiss Civil Defence plans worked well enough to allow the country to survive almost intact.
Reading the various posts it is reasonable to assume Germany sufferred the most with tactical and strategic nuclear attacks made on Germn territory both on and off the battlefields. Britain and the US came under a highly intensive attack as did most other European countries including France,
Given this there would be a question of how much government and infrastructure survived intact, Assuming the probable degree to which these suffered there is a question of the degree to which civil defence plans worked in places like the UK over the short, medium and long term/. Likely in some places the plans would have worked much perhaps depending on local personalities and decision making in the post attack period.
In some places the Civil Defence Plans would have worked well and these areas would likely have survived too become points of light in a new, post WW3 Dark Age. In other areas where people survve in significant numbers the Civil Defebce plans might not have worked so well. There is also a question of whether central government surved and, if it did, the extent to which it could maintain control over the regions. In the UK tthe plan seems to have been for 12 regions. If the 1984 government survived what is left of the UK will do fairly well although long term splits could well occur with some regions braking away. Germany nd much of central/Eastern Europe are for the most part just gone. The Soviet Union and US were probably helped by their size but might or might not have survived the post war period ithout breaking apart into constuent states.
The late 1980s and 1990s would, in particular have been a time of collapse as Dunnois says. How thigns go after that depend on how well things went since the war, In places there would be almost complete collapse, in others things migt hold together. I would expect nations suffering direct attack like the UK to have done quite well but may have broken apart. Germany would be in a far worse postion. With the battlefield/strategic exchanges and the fallout over the next few years many Germans be dead, probably most of them. Much the same for countries such as Poland. In these areas government would be virtually non exsistent with roaming bands of ex NATO/Warsaw Pact troops roaming about for years after the war. In short a situation worse than the 30 Years War. Eventually some would settle down as militar settlemenr=ts as there is really no other option. During the 1990s and early 200s this kind of thing might be behind the coalition of new states much as happeened during the post Roman Dark Ages. This would ponly be the start of processes lasting years, if not decades or centuries. A surving Switzerland coulod well become an imortant post war power with the pre war technology/knowledge base being largel intact Most of Europe however is, to some degree, in a new Dark Age which may or may not be as bad as the one following the post Roman collapse. How long this lasts depends on gow things go locally.
In other parts of the world I largely agree with Dunnoisalthough #i don't see why China is gone.Even if nuked it s size may help.
#in Europe, the US and USSR survivor societies are likely deeply traumatised and this may resullt in new belief syt=stems. These could well be more anti technolgy and defiatel anti nuclear. Thi may turn into a new religion or would profoundly affect pre war religions. Pacifism may see groth although against that would be potential for conflict over scarce resources.
