I believe you. My answer was my attempt at levity. Do you remember the drill in school of hiding under your wooden desk in case of a nuclear attack? If you are my age (62) you should. Since those times, we have all seen footage of nuclear explosions. I don't think those wooden desks would have helped much.

Anyway back to your point. Those threats you've shown are very real. I think we are still looking for several Russian suitcase-sized nuclear devices that disappeared several years ago.

This world is a very dangerous place.
