A more thorough explanation:

A treaty is a formal agreement between two or more countries. It is like a contract that is followed by the nations involved. Treaties are governed by international law and are considered federal law in the United States. This means that they are more important than state laws.

The President of the United States can make a treaty with the advice and consent of the Senate. This means that two-thirds of the Senate must agree to the treaty. However, the President can also make informal treaties with other countries by using executive agreements.

One example of a treaty is the Paris Agreement. This is an agreement between many countries to work together to reduce greenhouse gas emissions and combat climate change. Another example is the North Atlantic Treaty, which is a treaty between the United States and other countries to provide mutual defense.

These examples illustrate the definition of a treaty because they are formal agreements between countries that are followed by the nations involved. They are also governed by international law and are considered federal law in the United States.
