Now somebody remind me of what the Constitution and the Founding Fathers (most of them) said about foreign treaties.
Article II, section 2, gives the President the power to make treaties, with the advice and consent of two-thirds of the "Senators present"; Article I, section 10, forbids states to make treaties; and Article VI says that "all Treaties made, or which shall be made, under the Authority of the United States, shall be the supreme Law of the Land."
