|Looking into it, a 2/3 vote in the Senate is needed to approve the treaty. No way they could ram these treaties through with that requirement, which is not to say the Dems might not try some procedural wrangling to do it.|
In the US, the treaty power is a coordinated effort between the Executive branch and the Senate. The President may form and negotiate a treaty, but the treaty must be advised and consented to by a two-thirds vote in the Senate. Only after the Senate approves the treaty can the President ratify it. Once a treaty is ratified, it becomes binding on all the states under the Supremacy Clause. While the United States House of Representatives does not vote on it at all, the requirement for Senate advice and consent to ratification makes it considerably more difficult in the US than in other democratic republics to rally enough political support for international treaties. Also, if implementation of the treaty requires the expenditure of funds, the House of Representatives may be able to block, or at least impede, such implementation by refusing to vote for the appropriation of the necessary funds.
