I'm not American. There is a host of publicly available proof of Iran's pursuit of nuclear weapons. It is not, and has never been, a well kept secret of the regime.
The Pentagon agrees that Iran is not officially pursuing nuclear weapons. However, there are CIA reports that indicated there may have been covert operations taking place that were exploring cruder nuclear weapons. I imagine that was the basis for the US bombing of Iran in 2025.
JCPOA agreement was nuked by Trump administration. No, I don't buy your arguments, If Iran would wanted to have Nukes would have it already made those in 5 years for sure. Kim didn't have problems for making those.
