That is assuming everyone has a working survival instinct. Religious fanatics notoriously do not have this instinct. You just need one country with a religious fanatic at its head, who thinks that it is better we all go to heaven than to let evil win, and boom.

Now you can you argue the current US president is a fanatic if you want. But I do not see how adding more bombs to more countries reduces the odds of nuclear warfare in the future.

The current equilibrium has worked well enough. I do not see why we need to hand over nuclear weapons to countries currently embroiled in bloody civil wars.
