We have had a decade now of diplomatic negotiations over Iran's pursuit of nuclear technology in violation of the U.N. Security Council Resolutions on this subject. These have reached their height over the past year, as the Obama administration, along with the UK, France, Russia, China, and Germany, have been seeking to negotiate a "long-term comprehensive solution" to Iran's illicit nuclear program. During these talks, Iran has agreed to limit its nuclear program temporarily in return for some sanctions relief. A final agreement would free Iran of sanctions, while allowing it to maintain a "mutually defined enrichment program," to be treated like any other "non-nuclear weapon state party to the Nonproliferation Treaty." That best case would leave Iran as a threshold nuclear state. But worse, any limits placed on Iran's nuclear program as part of the "comprehensive solution" would, based on this agreement, expire. Maybe in 10 years, maybe sooner. But there is an expiration that is being discussed right now in the agreement.
