Specifically, the arms embargo is not tied to the snapback; it is tied to a separate set of obligations. So they are not in material breach of the nuclear agreement for violating the arms piece of it.

Reuters: Iran's senior negotiator made clear last month that Tehran had no intention of complying w/ the arms embargo & missile sanctions. — STEW (@StewSays) August 11, 2015

Kerry: "Moreover, after that, way into the future, we have 24/7 inspection of all their facilities" That is a lie. — Omri Ceren (@cerenomri) August 11, 2015

Secretary of State John Kerry would like to assure Iran that even if it violates the terms of the gratuitous concessions " thrown in as add-ons " to the nuclear deal, the regime won't be in violation of the deal as a whole. Remarkable Not to worry, Kerry explains, because there are "other sanctions" the US could impose -- plus, we mustn't forget about the "specific UN resolutions outside of this agreement" that prohibit the Iranians from arming groups like Hezbollah and Shiite militias operating in Iraq. Except Tehran has sent weapons to those proxies, repeatedly. Iranian explosives killed an estimated 500 American soldiers in Iraq. The regime has habitually ignored those international rules and obligations, with lethal consequences; they've been rewarded with a lopsided international deal that legitimizes their nuclear program and guarantees hundreds of billions of dollars in sanctions relief. Why on earth would they ever abide by a UN resolution again? They've been cheating on nukes during the negotiations, they've substantially increased their nuclear stockpile while their program was supposedly "frozen," and they're actively defying existing sanctions to this day. All with impunity. By the way, why does Kerry seem so keen on broadcasting to the world that certain elements of this accord are more violable than others? Because the Iranians have been broadcasting their overt intention to violate those very elements of this accord, of course:I'll leave you with this Straight-up false , on multiple levels
