I guess the crisis itself could be and was, but at the time nobody was really talking about the concept of a cold war, and the nuclear threat stayed heightened for decades. Actually, opinions vary on how long a nuclear-power conflict can reliably stay cold, even now.
AI and nuclear war seem like the main direct threats right now. Climate change will suck and I'll miss coral reefs, but it's not planet killing unless it sets something else more deliberate off. The world looks unstable, but I'm not expecting WWIII this year, and AI isn't going to be very dangerous by 2025 either. The Cuban missile crisis should have ended the world as we know it in the span of a few months. We basically just won a few coin flips in a row; I bet other parallel universes weren't so lucky.
My #1 issue with the Democrats. I'm not sure how they talk about unprecedented times so much without actually acting on it.
