Treaties Treaties are formal written agreements between countries. United States treaties are ratified by the president but require a two-thirds approval vote from the Senate. Executive agreements are similar to treaties and are made by the president but do not require the advice and consent of the Senate.
Bilateral treaties involve two countries, while multilateral treaties involve three or more.

This index supplements Treaties in Force by providing additional access points.
