The following is mostly a reply I gave in someone else's thread. I wanted to share it without risking the other threadfolk getting backlash.

Concerning whether or not US-Americans know and/or care that yesterday could easily have been the start of WWIII/a global nuclear event:

A lot of us care and are aware. Enough that we were checking the news every few mins yesterday & dreading the approach of 8pm EST.

Please don't paint all US-Americans with the same brush of dismissive judgment....

This is because smaller nuclear powers would be facing a zero-sum scenario while facing a nuclear superpower. Thus: MAD remains an effective deterrent.

What could proliferate is other tactical responses. US->Iran , then RUS->Ukraine for example. But such actions would only be seen as possible, without risking escalation, by the nuclear superpowers themselves. Smaller nuclear states would always be facing a zero-sum game vis a vis the nuclear superpowers. That is a numbers game. /2
