Congress is finally having its say on the Iran deal. It will be an elaborate charade, however, because, having first gone to the U.N., President Obama has largely drained congressional action of relevance. At the Security Council, he pushed through a resolution ratifying the deal, thus officially committing the United States as a nation to its implementation -- in advance of any congressional action.
The resolution abolishes the entire legal framework, built over a decade, underlying the international sanctions against Iran. A few months from now, they will be gone.
