No.
1) The allies of both countries would understandably freak at the idea that they can burn but the people deciding to do the burning are untouched.
2) Once one is used...
That's actually a fair point.
Paradoxically, I think the less connected and advanced you are the better you can get through The End. I think the biggest problems for those countries would be how much, if at all, the US or the Soviets back their government, supply them with food and monetary...
Oh, I don't question at all that the South will be better off than the North. But there will probably be a hard time as people adapt to losing the easy, cheap, outsourced stuff and deal with the fallout - real and figurative - of the mass suicide to the north.

And even if there weren't any US bases in western Europe, there are NATO bases and the countries' own bases. And even if they weren't hit all of the radiation, fallout, fires, refugees, civil...
It's more that 1983 Doomsday is FULL of painstakingly thought-out pop culture pages talking about everyone from Paul McCartney to U2 surviving the war and continuing their careers and touring across the world. I've even seen people contacting the real people and asking where they were on that...

As someone said, Threads gives you a good idea despite being set a decade plus later.
What people on this forum seem to want in stuff like the equally decade-plus-later 1983 Doomsday - a world full of quirky survivor states, a rich pop culture, and an increasingly recovering global civilization...
