Although Iran’s mastery of the nuclear fuel cycle presents an inherent option for creating a bomb, the Tehran regime has no urgent incentive to build nuclear weapons. Current U.S. policy, which emphasizes coercive sanctions and diplomatic isolation to compel Iran to comply with its obligations under the nuclear Nonproliferation Treaty (NPT), would fall squarely under the rubric of containment, even as the term has been eschewed and delegitimized in the U.S. policy debate. As long as Iran does not overtly cross the U.S. “red line” of weaponization, U.S. policy will likely remain containment in form, if not in name.
