When the Obama administration agreed to the framework for talks, critics in Congress and in the administration of Israeli Prime Minister Benjamin Netanyahu called it a terrible mistake. But six months later, it is impossible to conclude that the interim agreement has been anything but a success, even if it fails to produce a final deal by the deadline. The United States and its allies agreed to suspend some sanctions in exchange for a freeze on Iran's development of its nuclear capability, and by all accounts — even from members of the Israeli government — Iran has honored its commitment. International inspectors have better access to Iran's nuclear facilities, the nation has diluted most of its medium-enriched uranium, and it has agreed to changes to a heavy water reactor among other things. Even if no progress were being made in the negotiations, the interim agreement itself is making the world a safer place.
