The constitution, in Article II Section 2, gives the president the power to make treaties, but two-thirds of the Senate has to approve the treaty. I don't see how they can vote on it if they can't see it. (Even if they don't tend to read what they vote on, they have to be _able_ to read it.)<p>I suppose the entire Senate could be sworn to secrecy, along with their aides who do most of their reading for them, but I'm sure a bunch of them will object to that and vote no. And even if they don't, sooner or later the law has to be made public so it can be enforced, so any senators who vote for it will be held accountable. (To the extent they're ever held accountable for their votes.)<p>So this may be classified now, but I don't see how it can remain that way if it's going to become a treaty. It'd have to become a classified executive order that's not subject to congressional approval. That may not satisfy whoever is pushing for a full-fledged treaty, though.
