You know nothing of geopolitics. Saudi has explicitly said they will also immediately develop one, and you’ve just proliferated nukes into the hands of regimes that have no problem acting bellicose like Russia. China and Russia also signed the JCPOA. If you want the rest of the world to go “why can’t I have nukes and invade my neighbors” then that’s on you. But stability it is not.
