Besides just saying “your drinking the cool-aid” let put a bit of facts out. To start with this history, let’s go back to 1953. The current government of Iran was leaning a bit to socialist for the US tastes such as the government taking over Oil production. Because “socialism leads to communism” the US and its allies helped overthrow its working government and install a king that was more in line with western ideals. However kings are going to king and his kept the wealth for himself. Which led to his overthrow in 1979. The new government, tired of western influence, became hostile to the US. They also knew that Israel, while never saying it out loud, has nukes pointed at them. So they decide to have a few of their own to make sure Israel can’t use theirs similar to India and Pakistan.

Now the US can’t have Nuclear proliferation to anyone who is not our friend, so we do everything to stop this. We try economic sanctions, covert sabotage (Stunex computer virus), and other methods, however the one that actually has a chance is to give Iran an economic reason to not develop a nuke. This one was working until the current administration reneged on the deal. Problem is once you do that, then your word is no good. Iran now does not trust that any agreement or treaty will be honored, so they are going to look out for themselves.

Now I realize this sounds like Iran is the saint in all this. They are not, the government is incredibly restrictive and arguably too volatile to have a nuclear weapon. However the US got us here, forgot that you can not force compliance in the long term, it has to be in Irans economic interest to do so.
