Stop grasping, you're making yourself look silly. You asked if President Bush "knew" if the Senate had to ratify treaties.
Well, the fact of the matter is that President Clinton signed Executive Orders that *forced* all federal government agencies to behave as though the Kyoto Treaty *had* been ratified, even though it hadn't.
President Bush repealed those XO's, and Bush also pulled the U.S. out of the whole Kyoto ratification process.
Does none of this matter to you? Are you so opinionated and biased that you won't even give President Bush credit for duly killing the Kyoto Global Warming treaty?
