I know there have been quite a few posts on this topic due to recent media surges about Russia/Ukraine, but I’d really appreciate some insight or reassurance. 

Every year when a global conflict starts to stir and talks of nuclear war or WWIII ramp up, I’m sent into an absolute panic that consumes my mind and can’t seem to kick it. 

I’m well aware that because I live in the US, these are typically not things I need to be concerned with for my immediate safety. That said, I can’t help but perseverate on the idea that one day someone will just say “screw it” and “press the button.”

Any books, articles, or resources on the subject of geopolitics and all this stuff would be appreciated. Thank you all in advance.
