Why and how to tighten the screws on Iran

Two years ago, nuclear negotiations concluded between Iran and the P5+1 group of nations, with the U.S. at its head. The resulting Joint Comprehensive Plan of Action, or the Iran nuclear deal, has accomplished little in the time since.

Some may argue that the agreement succeeded in slowing Iran’s progress toward a nuclear weapon. But the restrictions on the Iranian nuclear program are limited, as is the access that international inspectors have to the country’s illicit facilities.
