US to station nuclear weapons in UK to counter threat from Russia. Old enough to remember how libs were saying Belarus was being colonized when Russia put nukes there.
There's a movie called Threads that starts out like that. If you haven't watched it, do. It's the most realistic depiction of nuclear apocalypse you'll get to see.
A little less realistic, as it starts as animation before slowly incorporating live-action footage as things get dire and more depressing, but When the Wind Blows is also a very good depiction of what happens to regular civilians during a nuclear war. Distressing and depressing film, but a good one.
People sometimes get mad at me for saying there is no such thing as Europe, UK, Australia, etc but things like this happen and I am left with no other choice but to continue believing it.
