This “agreement” is not a treaty, it has no legal or moral validity, since, had it been submitted to the Senate, it would not have been ratified.
The purpose of treaties going to the Senate, and requiring a supermajority for ratification, is so that the States are not bound against their will to a foreign arrangement (remember, Senators are supposed to be ambassadors from their States).
The President has no authority to treat with foreign powers in a way that binds the States. And, as Congress has the sole and exclusive power to legislate for DC “in all cases whatsoever”, the President alone has no authority to bind even DC to a foreign power.
Well stated. And remember...Corker made this deal such that it did not have to go to the Senate. Another traitor.
