the Senate
The treaty between two countries is typically signed by representatives of each country's government, often at the level of heads of state, foreign ministers, or designated diplomats. These representatives must have the authority to bind their respective governments to the terms of the treaty. Additionally, the treaty usually requires subsequent ratification by the respective legislative bodies or governing entities to become legally binding.
The two significant treaties signed by the United States to resolve conflicts with foreign countries are the Treaty of Paris (1783) and the Treaty of Versailles (1919). The Treaty of Paris ended the American Revolutionary War, recognizing American independence from Britain. The Treaty of Versailles concluded World War I, establishing peace with Germany and redrawing national boundaries in Europe.
The power to enter into treaties with other countries and make executive agreements with other heads of state is known as the power of foreign diplomacy or treaty-making authority.

In the United States, the power to approve a foreign treaty with foreign countries lies primarily with the President and the Senate. The President negotiates and signs treaties, but they must be ratified by a two-thirds majority in the Senate to become legally binding. This system ensures a balance of power between the executive and legislative branches in foreign relations.
