I agree. Having plutonium and making a bomb out of it are two very different things. Everyone knows how to make a nuclear bomb but only a few have the technology to combine two nuclear masses into one mass efficiently.
Pakistan had the nuclear material for a long time and couldn’t make a bomb out of it until a scientist from South Africa sold them the triggering technology. He went to jail but got out a few years ago. He should have been put to death.
7 tons of plutonium? I doubt that. But I do not doubt he would sell it to Iran as part of his escape plan when Trump ends the Great Grifting War.
