The President does not make treaties. Congress does. This includes the Senate as well as the House of Representatives.
The Senate has the right of ratification.
The Secretary of State negotiates treaties but they must be approved by the President and ratified by the Senate.
The president can negotiate treaties, but they must be ratified by the senate to go into effect. He can appoint ambassadors, and they also must be approved by the senate.
Treaties are approved by 2/3 of the SENATE!
Through the Department of State and the Department of Defense, the President is responsible for the protection of Americans abroad and of foreign nationals in the United States. The President decides whether to recognize new nations and new governments, and negotiate treaties with other nations, which become binding on the United States when approved by two-thirds of the Senate. The president may also negotiate "executive agreements" with foreign powers that are not subject to Senate confirmation. I believe the president can negotiate treaties, but they do not take effect until the Senate votes to ratify them.
All treaties must ratified by the Senate before they take effect.
