enumerated powers
The executive branch negotiates treaties. The Senate must approve those treaties. The answer can be found in Article II Section 2 of the US Constitution. It reads: "He shall have Power, by and with the Advice and Consent of the Senate, to make treaties, provided two thirds of the Senators present concur" (He is referring to the President.)
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.
The President of the U.S. has the power to make treaties with foreign countries, but must be confirmed by the U.S. Senate. He also has the power to enter into executive agreements (secret treaties) with no Senate confirmation needed.
The Senate.
Yes
true
It is the Secretary of State's job to negotiate treaties.
In the United States, that power is vested in the President, but the treaties must be approved by the Senate. This is Article II, Section 2, Clause 2, of the Constitution.
enumerated powers
The Senate has the right of ratification.
Yes, of course the president can. I believe it was the Louisiana Purchase that the president bought without asking the congress. When asked that the president did not have the power to buy the land. He said that he did have the power to "negotiate" treaties.
Diplomats negotiate treaties, government officials sign them, and national legislatures ratify them.
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.
I think you are talking about Benjamin Franklin.
The Executive Branch makes the Treaty, this branch includes the President, the US Senate ratifies the Treaty by a two thirds majority. Only then is it effective.
