It's generally believed that they don't yet have weapons. They may not even be actively working on weapons. What they are doing is building the infrastructure necessary to create weapons, and that cannot be allowed unless that infrastructure is subject to a level of inspection adequate to guarantee it is only being used for peaceful purposes.There you have it.
They have no weapons.
No. The inspections they are subject to right now are UNABLE to confirm that. There is a huge difference between the IAEA saying "we found no evidence" and the IAEA saying "we found no evidence, after a thorough inspection". At the moment with the lax inspections Iran allows it is possible the IAEA found nothing only because Iran has it well hidden.Are under inspections to confirm they aren't using uranium for weapons.
Fill compliance with the Additional Protocol would provide some suitable guarantees that Iran is not hiding anything. It's not voluntary or optional for Iran, it is mandatory.
Yes, and for a fucking good reason.The UN SC is holding them to an agreement they didn't ratify.
