Obama's Coming Gun Control: Through the UN

Why is this being reported as though the treaty does not require senate ratification? Since when can the executive promulate an international treaty without senate ratification? What is going on in the senate that makes these reports come across as though the senate will ratify? I do NOT see that happening. Unless I am missing some huge elephant in the room about the process, I can only see a huge dose of scare mongering going on by articles such as this. The NRA and all the sister oeganizations would have senate heads on pikes if this passed that chamber. I do doubt this is going anywhere.
