Treaty
A treaty is a formal international agreement governed by international law. Under Article II, the President makes treaties with the advice and consent of two-thirds of senators present; the United States also enters other international agreements under different legal authorities.

Example: The North Atlantic Treaty, which established NATO, was submitted to the Senate and received the required advice and consent in 1949.
Common misconception: Every international agreement is an Article II treaty. The United States also makes congressional-executive and sole-executive agreements under other authorities, and their legal basis differs.
