I love how subversive and dark this song is (for a shameless 80s pop gem)...
If you want to despair at the human race, look at the comments below it. Classic Youtube idiocy. People arguing not over whether the song is about nuclear war or not, but over whether it's about a nuclear war started by the US or by the USSR. If there is one thing that renders that argument completely irrelevant, it's probably mutually assured destruction, to be honest. Chrissakes, that's not just missing the point, that's actively being completely fucking oblivious to it.
Fuck this shit, I'm going for a bike ride.
