What describes an agreement between the president and the leader of another country?

An executive agreement is a formal agreement between the president of the United States and the leader of another country that does not require Senate approval, distinguishing it from a treaty, which does require such approval. This type of agreement is often used for negotiations on issues like trade or military cooperation and provides the president with the flexibility to engage in foreign relations without the lengthy ratification process that treaties necessitate.

Executive agreements are binding and carry the weight of law, making them an essential tool for the president to conduct foreign policy effectively. The use of executive agreements has become increasingly prevalent in modern governance as presidents respond quickly to changing international dynamics. This mechanism allows the U.S. to maintain diplomatic relations and agreements efficiently.
