There is the possibility that the President can sign this treaty, and wait until after the 2014 midterm elections to try to have the Senate ratify it, hoping the balance of power shifts more to the left in the Senate by then. I believe there is a statute of limitations between signing and ratifying dates of treaties, which afterwards they become invalid, although I am not certain on the exact time frame alloted. Although it has been debated here previously, on the constitutionality of a ratified UN treaty affecting domestic 2nd ammendment rights, the Supreme Court will ultimately deceide. We have won the last few 2nd ammendment related court decisions 5-4. During the President's term, if he replaces one of the conservative justices, it will tilt the majority, and he will have a court that will rubber stamp anything anything he wants as being constitutional.
