Hope so. It's just that all the Mutually Assured Destruction stuff depends on some level of rationality, and we seem to now have a Putin who is acting very irrationally and allegedly with senility involved so that's what has me worried that one escalation will lead to another
I mean, I'm not suggesting anyone else should. If anything, perhaps mentioning the idea was a cry for help from someone who may be thinking more clearly (so to just effectively get a slap for it is unhelpful). But, as the results of my google search suggested, it might not be a great idea to have some kind of "easy euthenasia device" because sure, to me I think it's quite rational to prefer the idea of a painless death to one limping around a wasteland, possibly blind, slowly dying of radiation poisoning and starving. But, if things don't go that far, you still have that thing around that could make a bad day unnecessarily extreme in a bad frame of mind.
