Word was also spread around that it was polluted with nuclear crud etc so wasn’t worth taking back. The explanation that all the Finns had left 100 years ago makes more sense (though the nuclear pollution argument is sadly at least plausible - USSR was not particularly careful in that regard)
edit: This is what Stalin did to most non slav peoples in Russia close to any major/important city or resource. (in this case Saint Petersburg)
Russian military is also brainwashed with their pseudo-scientific geopolitical propaganda, your army simply can't work well if it thinks that bullshit is true, just look at the idiotic "tactics" they're using right now.
Also, I think the technological gap is now simply too large. The recon capabilities of today + various types of UAV and new kinds of manned aerial vehicles, coupled with new generations of weapon systems, could very well mean we would pluck the nukes from the sky mid-way.
As far as I know, no country today has a viable anti-ballistic missile defense system that works well enough to stop even a small percentage of the number of nukes that would be triggered by a MAD style endgame. What technology are you talking about?
I’ve also never heard of a defence system that can pluck that many missiles out of the air. The closest I’ve heard of is the Iron Dome - which would not be able to stop what you’re talking about at all. I would think the nation that has that capability would make it known for geopolitical reasons.
Their bombs are rusted!!! What kind of operation are they running FFS? https://twitter.com/ukrpravda_news/status/149767369139567001...
Seems like the most likely course of their nuclear attack is, they blow up themselves because the doors rusted shut.
