The Doomsday Clock that (arbitrarily) illustrates how close humanity is to an apocalypse remains stuck at three minutes to midnight. The clock was invented as way to point the precarious nature of the Cold War’s Mutually Assured Destruction. With more than enough nuclear weapons in the hands of the two superpowers (US and USSR/CCCP), an Armageddon had never been closer. Now that the Cold War is over, the threat should be diminished, but more than enough weapons remain, too many of them aren’t protected properly, and too many countries have them. The original scope has expanded to reflect the danger from climate change. Improvements in Iran are offset by instabilities elsewhere. Improvements in the Paris Accord are academic so far. The clock is arbitrary, yet it continues to represent the subjective judgment that we have to be careful, vigilant, and not complacent.
