Do you stab at each other ?

New nuclear powers will continue increasing unless all nuclear powers abandon the nuclear weapons. And it is impossible that the nuclear powers abandon their nuclear weapons.　Because they cannot abandon a sense of fear and suspicion.
Nuclear powers gradually increase, and the majority of countries come to have the nuclear weapons and the intercontinental ballistic missiles finally.

It is very dangerous that old-timers try to stop newcomers by force.　Because it is very likely that the other country already has the nuclear weapon. Even if it is a superpower, the economy is completely destroyed by attack to the big city that used a dozen of nuclear weapons. Old-timers must be ready for striking each other simultaneously.
