The Iranians were testing their design for using explosive 'lenses' to compress plutonium for a nuclear bomb. Even I can figure that one out. Will they build bombs, or just perfect the technology for a rainy day (a.k.a. invasion by forces of the Great Satan, or his Sunni Muslim oil suppliers)? Who knows. It would be counter productive to build an actual weapon because they become less safe by becoming a nuclear target from across the Persian Gulf, where they seem to think they have a lot of "enemies". (They have a LOT of "enemies" as you may have noticed in their newspapers.) I doubt they will need a nuke to keep the Taliban in Afghanistan at bay. No country in the area can really threaten Iran with invasion. And defying that fatwa against building nukes might be hazardous to your health inside Iran. If it wasn't so dangerous, it would be quite funny. Like what else were they doing in that building that they tore down? Testing a new paint color that turned out to be really ugly?
