From the bill:
An action involving statutory sanctions relief by the United States pursuant to an agreement or the Joint Plan of Action:
may be taken if, during the review period, Congress enacts a joint resolution stating that Congress favors the agreement;
may not be taken if, during the review period, Congress enacts a joint resolution stating that Congress does not favor the agreement; or
may be taken if, following the review period, there is not enacted any such joint resolution.
Of course, any other protections supposedly afforded by the bill have been ignored, with OZero already working with the UN to drop sanctions within the review period and without congressional repercussions.

The problem with your position is that it requires you to conclude that every republican in the senate(except the single no vote Tom Cotton) is in cahoots with Corker and equally guilty of what you accuse Corker of being guilty of.
