Not really.
Not for the middle east anyway.
Although I see your point about having nuclear weapons resulting in less wars. The USA and USSR never actually got in a direct war.
OTOH, if just one reckless leader decides to use nukes, just for once, it will probably start an endless nuclear war.
It's a double edged sword.
Wonder what would happen if every country in the middle east had them, or say, major countries (Turkey, and some Arab country).
