The text of the interim agreement with Iran explicitly and dangerously recognizes that Iran will be allowed to enrich uranium when it describes a 'mutually defined enrichment program' in a final, comprehensive deal. It is clear why the Iranians are claiming this deal recognizes their right to enrich. The U.S. should not weaken existing United Nations Security Council demands that Iran fully suspend its nuclear activities, including enrichment. Loosening sanctions and recognizing Iran's enrichment program is a mistake, and will not stop Iran's march toward nuclear capability.
