Why does this very obvious point fail widely to preoccupy people? There *was* a widespread understanding of the risk during the Cold War. And he's right: While it's impossible precisely to quantify the risk, rational assessment suggests it is now much higher.
There are more nuclear powers. The established powers are racing out of stabilizing treaties and introducing new, destabilizing technologies. The leaders of the nuclear powers are visibly irrational and reckless.
One would think that the threat of nuclear Apocalypse would be high on people's minds--at least as high as the threat of climate change, about which we know a lot less.
