Six Western countries and Iran on Nov. 23 struck an interim agreement in Geneva that will restrict Iran's uranium enrichment and partially lift some of the Western economic sanctions against Iran.

This represents the first concrete result of seven years of negotiations over Iran's nuclear program between Iran and the "P5-plus-1," which comprise the five permanent members of the United Nations Security Council — the United States, Britain, Russia, France and China — plus Germany. But it is only a six-month interim deal that will only temporarily curb Iran's nuclear development program.

Iran should make sincere efforts to dispel international concerns over its nuclear program by fulfilling the terms of the accord, including acceptance of the daily monitoring of uranium enrichment facilities at Fordow and Natanz by International Atomic Energy Agency inspectors. U.S. President Barack Obama, for his part, should persuade those opposing the deal, including Israel and members of the U.S. Congress, to support it.
