Knowing this was filmed in 2020 or earlier, we know who was President. This movie plays on the theme that the US would be drawn into many wars and sought to scare us that the Orange man would cause nuclear war. The toxic rhetoric of the President is how it's put, or close to that, before any action begins in the nuclear way of things.
I mention irony because no matter what your position on the sliding scale of politics, one would have to be willingly lying to themselves to not understand how much closer the world is to such a disaster today.
At any rate, I was thinking this might be like the movies from the 80s. I'm terrible at remembering the movie names usually but I think The Day After was the American film with Jason Robards but the British film title escapes me. Both were grim looks at the closest a film could make nuclear war appear as it might be in reality. Something like that I hoped for here...turned out to basically be what General Hospital would've done with a nuclear storyline...except I rather enjoyed some GH back in the 80s.
