Here we see the Kakistocracy in full bloom.
Can such an entity deter its own nuclear annihilation by posing a threat of a swift counterblow. Can the evil such an entity represents create such fear and loathing that it undermines the fear of retaliation that it depends upon for its depradations on the world.
How can such an entity tell that it has pushed so far that it's deterrent is now a pointless gesture in the effort to save itself from the world annihilation that it's nihilistic culture is striving?
Are you reaching that point when the other two great nuclear powers point out that you are the threat to world peace directly participating in endless war for well over a century? Are you straining the world's patience when asking "give peace a chance" you have engaged in endless war, with barely a pause?
