Somewhat synchronistically, the first performances of the song coincide with the release of the movie Terminator 2 Judgement Day, which contains a disturbing and scientifically researched portrayal of a nuclear detonation over the city of Los Angeles USA.

Fast forward 26 years to when the studio version was being recorded, and we find President Trump pulling out of the nuclear non-proliferation treaty with Russia and Los Alamos gearing-up for renewed nuclear weapons production. A Russian missile testing facility also blew-up causing several radioactivity monitoring stations to go offline, and the Doomsday Clock was closer to midnight that it had been since the peak of the Cold War. Yes folks, this was all happening in August 2019. To top it off, Terminator Dark Fate was then released in November.
