Step-by-step explanation:
The subject of this question is Social Studies.
In the United States, the power to make treaties with other countries rests with the president, subject to Senate approval. According to the Constitution, the president has the power to negotiate treaties, but they need two-thirds of the Senators present to concur for the treaty to be ratified.
Additionally, the president may also enter into executive agreements with foreign powers. Unlike treaties, executive agreements do not require Senate ratification and are considered enforceable as long as they do not conflict with domestic law.
