Here it comes. The President will sign it and expect the Senate to do the same in kind. He will shame them and blame them for violence around the world if they don’t.
I've heard that there is some trickiness in international law that says that if a country signs a treaty it in in force unless in is specifically not ratified by that country's legislature. That is the opposite of what the Constitution specifies that the President can make treaties only with the advice and consent of the Senate.
There are a lot of signed treaties that have never been brought before the Senate because they would likely be rejected and this will be added to the pile. Then Obama will try to treat it as if it has the effect of law.
If the Republicans ever get control of the Senate again, they need a session just to vote to reject outstanding treaties which won't be ratified. Clear the deck of the junk.
