Trump Waved Off Israeli Strike After Divisions Emerged in His Administration

Libya and Ukraine are two warning examples what happens if you give up your nukes. There is no reason for Iran to trust this US administration or any other administration to come.

So Iran at the very least will try to maintain a level of being ready to develop and build a few nukes in a short time frame, if any outside threat would become more serious. In order for Iran to not feel such a threat to manifest, the whole power dynamics in the region would need to change fundamentally. But with Saudi Arabia, Israel and Turkey being strategic threats and Israel also having nukes, i don't see any scenario where Iran would not have reasons to feel threatened.
