If there were a broadcast stating that Russia just launched multiple ICBM all aimed at the US would you go into panic, cry, and feel distressed in the last few moments of your life or would you accept the fact that the pain, suffering, and loss would be coming to an end? I personally would call all my family to share my last moments speaking with them. I would be happy as I feel the world is currently on fast track to armageddon. All the degeneracy, violence, lack of empathy would be gone and a new civilization would rise from the ashes. I do wonder if the cycle will repeat.

These are things that we would have no control over. By the time we have knowledge of nukes headed to our location, there is nothing we could do and it would be too late to flee to safer locations even if we knew what they were. I’d assume there are nuclear fallout shelters that one could hope to escape to.
Disregarding the fallout shelters, I’d most likely call all my relatives and stick with my friends till the very end, maybe reminisce about our lives.
