Don't forget that the "nuclear club" has a pretty solid double standard where they perfectly legitimize having their own nukes and last I checked the official NATO and Russian policy is that they can respond to any attack, conventional or nuclear with nuclear force while they strongly work for non-proliferation to prevent others from having the same weapons at their disposal. They trust it so much they very strongly don't want anyone else to join the "MAD club", why do you think that is? Because they know the whole thing is fickle as hell and someone might end up pushing the button
You'll get no argument from me there. It's not a great solution by any means, but seems to be the most realistic at the moment.
Too many people are thinking of security instead of opportunity. They seem more afraid of life than death. -- James F. Byrnes
