Does This Mean That Iran Will Be Limited to Just a Couple of Nuclear Weapons? Or That Iran Will Only Be Allowed to Use Its Nuclear Weapons in Agreed-Upon Circumstances?

An odd turn of phrase in this David Ignatius column (which I assume he doesn’t mean the way it sounds):

Obama’s approach is part of a big strategic idea for the Middle East that could be described as “dual engagement.” On the one hand, the United States is seeking an agreement with Iran to limit its nuclear weapons. On the other, the United States wants to bolster the Saudis and their neighbors through new U.S. military commitments. The goal is an eventual balance between a less-threatening Iran and a more confident, forward-leaning Saudi Arabia.
