I don’t care about Ukraine. The Russian nukes in Russia (Ukraine last week) are the trip wire. The missiles, initially, are hopefully aimed at only NATO military targets. Although that really doesn’t matter as it would quickly escalate into a general exchange. You should read Herman Kahn’s On Escalation. What the hell? Forget reading On Escalation, you’ve watched it play out to the near bitter end.
There is zero chance of nuclear war, imo.
Bur if the world does end in radioactive fire, you can say you told me so.
Why would the Russians want to waste their nukes on our cities when our cities are already doing a fine job of self-destructing on their own?
