The Iranian government has repeatedly made compromise offers to place strict limits on its nuclear program beyond what the Non-Proliferation Treaty and the Additional Protocol legally require of Iran, in order to ensure that the program cannot be secretly diverted to the manufacture of weapons.[238] These offers include operating Iran's nuclear program as an international consortium, with the full participation of foreign governments. This offer by the Iranians matched a proposed solution put forth by an IAEA expert committee that was investigating the risk that civilian nuclear technologies could be used to make bombs.[34] Iran has also offered to renounce plutonium extraction technology, thus ensuring that its heavy water reactor at Arak cannot be used to make bombs either.[239] More recently, the Iranians have reportedly also offered to operate uranium centrifuges that automatically self-destruct if they are used to enrich uranium beyond what is required for civilian purposes.[240] However, despite offers of nuclear cooperation by the five permanent members of the UN Security Council and Germany, Iran has refused to suspend its enrichment program as the Council has demanded.[241] Iran's representative asserted that dealing with the issue in the Security Council was unwarranted and void of any legal basis or practical utility because its peaceful nuclear program posed no threat to international peace and security, and, that it ran counter to the views of the majority of United Nations Member States, which the Council was obliged to represent.
