To be honest, Israel can’t stop Iran from having nukes. That moment has passed.
Iranians are a sane bunch. Them getting nukes would give them a sense of security.
Think on the flip side. They are under iron clad sanctions that the Arabs/Israelis lobby for. They have not given up the Palestinian cause (the Arabs have long forgotten).
My opinion, Iran having nukes, would create an equilibrium (Israel has nukes). The Arabs and Israelis would cool down on their overtures against Iran and Iran might cool down with the support of Hezbollah proxy support as the threat perception goes down.
With respect to Pakistan, I believe Iran having nukes would result in a strong Iran which would mean less of proxy games and less trouble for Pakistan next door. As if Afghanistan and India ain’t enough.
Not a zero sum game but hope you get the gist.
