Tulsi Gabbard says Iran could produce nuclear weapons "within weeks", months after she testified before Congress that the country was not building them. The US Director of National Intelligence said her March testimony - in which she said Iran had a stock of materials but was not building these weapons - had been taken out of context by "dishonest media".
As nice as that would be, the unfortunate reality is that’s just not a realistic solution. You can’t put the cat back in the bag, so to speak.
The technology is already known; If everyone agreed to disarm, each party would just be even more worried about nations potentially ignoring that agreement and their now lack of defense against it.
The biggest reason I’m not all that concerned about Iran having nukes is the fact that so many nations are already nuclear armed. The use of nuclear weapons is so hated globally that they can only really be used in defence. If any individual nation chose to use their nukes offensively, the inevitable response from everyone else would mean the decision is suicide.
If Iran acquired nukes, then used them on say, Israel; America at the very least would turn Iran into a nuclear wasteland. I’m sure there are other nations that would join in, even if just on principle.
