The Iran deal could be a good deal.
If Iran complies.
Critics are doubtful.
The happiness of mullahs should give pause to those who support the deal.
The agreement legitimizes Iran’s nuclear program, allows it to retain core nuclear facilities, permits it to continue research in areas that will dramatically speed its breakout to the bomb should it choose to flout the deal, but also enables it to wait out those restrictions and proceed to become a nuclear threshold state with full international legitimacy.
Flout the deal.
Critics expect it.
History shows that's what Iran will do - they've done it since 1979.
