The value of having nukes is the other guy knows he will pay a horrific price.
Hence the value of reminders.
True. But those that actually operate them are not under the misbelief that these weapons mean anything but death if used, for them and theirs as well as the enemy.
Having them is to not use them.
I’ve only ever worried about a madman using them. Putin isn’t a mad man, and Biden really can’t order their use either. His handlers are smarter than him.
Someday? Maybe.
