The Iran deal is supposed to constrain Iran and prevent them from going nuclear. In the short run the deal is supposed to tie Iran up in knots. In the long-term, within a decade when the deal expires, Iran is supposed to become a responsible regional power that would never ever want to nuke anybody.
But look who is constrained by the deal:
Iran formally requested a meeting of the commission that oversees its nuclear deal with world powers to complain about the renewing of sanctions by the United States, state television reported Saturday.
The request was made in a letter by Foreign Minister Mohammad Javad Zarif to the European Union's foreign policy chief Federica Mogherini, calling for "a meeting of the joint commission outlined in the nuclear deal... regarding the recent actions of the United States."
The joint commission to enforce the deal is composed of America, China, Russia, Britain, France, and Iran.
So already Iran has 3 votes given that Russia and China run interference for Iran. We have Britain, I imagine. Lord knows which way France will go.
Heck, I'm not even sure which way our delegation will vote, truth be told.
So who is constrained by this nuclear deal, anyway? Don't bother. It was a rhetorical question.
