A report by the IAEA (International Atomic Energy Agency) shows that Iran now possesses 2,427 kilograms of enriched uranium. This uranium is currently enriched to the 3 to 3.5% range. This is enough uranium to power two nuclear warheads.
Iran has been toying with an IAEA offer to export 1,200 kilograms of enriched uranium to Russia in exchange for processed fuel for Iran's research reactor. The Iranian regime delayed these negotiations with a seemingly endless stream of lies and misdirections until it had processed enough fuel for a second nuclear weapon.
Iran would now possess 1,227 kilograms of enriched uranium after the peace deal, more than the 1,000 kilograms required to power a nuclear warhead. Now that Iran has enough enriched uranium for a "spare" nuclear weapon, they are now offering to complete the deal with the IAEA.
The deal would now achieve nothing in terms of limiting Tehran's ambition to obtain a working nuclear weapon, but would give the Iranian regime fuel rods for their reactor. The deal would be a major coup for the Iranian regime while offering no benefits to world peace. Iran has now enlisted agents in Turkey and Brazil to promote the deal.
Tehran also maintains a separate program to enrich uranium to the 20% level. The IAEA discovered equipment involved in that project at the Jabr Ibn Jayan Multipurpose Research Laboratory in Tehran, but the Iranian regime has since moved the equipment to a secret location. The missing equipment is capable of pyroprocessing, one technique for purifying uranium for use in nuclear warheads. The Iranian government admitted to pyroprocessing activities in January and then denied the same activities in March.
Iran has refused to stop enrichment activities and continues to enrich fuel for use in developing nuclear weapons. Only portions of it's nuclear program have been revealed to the IAEA and Iran has been caught lying to the agency on several occasions.
For it's part, the IAEA "remains concerned about the possible existence in Iran of past or current undisclosed nuclear related activities, involving military related organizations, including activities related to the development of a nuclear payload for a missile."
