Iran has had a few nukes for a really long time, probably what was left of South Africas..they claimed disassembly after the npt..but isreal also probably got a couple from them cause they did the whole double flash thing around about the time irans sha got the boot..coincidence…idk…but there is an amout of ambiguity behind those african nukes…not to mention what coulda went missin when the soviet union fell. I think they have a few very old cold war era nukes that have zero electonic activation links and they have been desperately trying for years to find a way to weaponize them and nobody is willing to give them what they want rocketry wise or actionable technology and targeting otherwise…or…they have old ones that have had their fuel removed and iran is attempting to enrich material now that they have gotten some kind of vehicle to move and target and they are trying to reverse engineer a very old warhead with new material capable of reaching critical mass upon detonation…they coube developing something new and home grown…but…their abilities have been…sub pr at best when it comes to in house innovation..this is a theory…and im probably wrong..or i hope i am anyway😐🤷🏻
