OIf course the Iranians are developing atomic weapons, the dumbest person on Earth knows that.
Why all the secrecy, why don't they let inspectors in to see every last detail of their nuclear programme?
Because they are developing atomic weapons. If they wanted a nuclear power station or 2 there are several countries that would sell them to the Iranians if sanctions were withdrawn, but they don't use the same technology as atomic weapons.
The Iranians are self-destructing, only a matter of time now, loopy economic policies, subsidies, hardline religious dictatorship, a trashed currency, and selling oil at any price for cash according to the latest news.
