I think it’s 1000% certain they have Israeli special forces in Iran . Perhaps they may have some Delta force mixed in with the Israelis. But I don’t think in the country that big you’ll be able to find Nukes because I think the whole purpose is to simply stabilize the regime
If the main reason for the war is to ensure that Iran NEVER has a nuke then an objective is to remover all viable fissile material. You just can’t leave the stuff there no matter whos in charge.
