I have increasingly read this too.
We also have to acknowledge that the intent with which a nation approaches it's nuclear strategy counts hugely. The in equivalences of the respective nuclear defence systems the US and Russia employ was already 'tested' back in 1983, when a Russian colonel chose to ignore the system flagging an incoming 'attack' by using a sense of both the situation and an intuituve knowledge of his own system's potential for errors. I have to wonder what would happen the other way? I wish everyone could at least employ the same tech for their nuclear defense systems...whenever discussions about who/how a nuclear war would/could be started and by whom, it's futile. We have no idea. None. And let's be honest, if an attack centered on a major city any of us lived in, we'd still have no idea because we'd be done in a (literal) flash...
...when my Mum was alive, she and my set-Dad moved into a nice place near Aldermaston. My step-dad recently showed me the 'guide book' which came with tyhe house purchase given how close it is to a massive AWE site. It was hilarious. 'Hide under your dining room table', etc. I mean, I suppose they felt they had to do something, but talk about an illusion of control and safety!
