I'm not trying to be snide, but this feels more alarmist than ever. I feel like we're further away from nuclear war than we have been in a long time. We have a lot more wars-by-proxy to fund war industries in the US, EU and Russia, which is a huge problem within itself, but far as the nuclear death of the planet, I feel like we've been in solid fear of mutually assured destruction for quite a while.
There is no real science behind the doomsday clock. It's literally an argument from authority, and I think it should be challenged.
