Iran should read the US Constitution. There is no treaty unless and until a proposal is approved by a 2/3 vote in the Senate of the United States.
This is part of the checks-and-balances our Founders built into our Constitution, to protect us from a president someday making a bad or sell-out treaty that endangers America.
(WOW! Those folks were sure prescient, weren’t they!?)
From Zavid's letter, I'm confident they'll let Barry's signature and multi-billion dollar sign-on bonus stand as the official US position on the matter, irrespective that they will continue their cheating ways regarding matters pertaining thereto.
I believe impeachment articles must be presented and passed immediately; let the chips fall where they may, even if that seems to do little more than identify Democrat Senators that self-proclaim as traitors to the Constitution.
