The U.S. Constitution does not explicitly give a president the power to enter into executive agreements. However, it may be authorized to do so by Congress or may do so on the basis of its foreign relations management authority. Despite questions about the constitutionality of executive agreements, the Supreme Court ruled in 1937 that they had the same force as treaties. As executive agreements are made on the authority of the president-in-office, they do not necessarily bind his successors. In the United States, executive agreements are binding at the international level when negotiated and concluded under the authority of the President on foreign policy, as commander-in-chief of the armed forces or from a previous congressional record. For example, the President, as Commander-in-Chief, negotiates and concludes Armed Forces Agreements (SOFAs) that govern the treatment and disposition of U.S. forces deployed in other nations. However, the President cannot unilaterally enter into executive agreements on matters that are not in his constitutional jurisdiction. In such cases, an agreement should take the form of an agreement between Congress and the executive branch or a contract with the Council and the approval of the Senate.  The U.S. Supreme Court, United States v.
Pink (1942) found that international executive agreements, validly concluded, have the same legal status as treaties and do not require Senate approval. To Reid v. Concealed (1957), the Tribunal, while reaffirming the President`s ability to enter into executive agreements, found that such agreements could not be contrary to existing federal law or the Constitution. Most executive agreements were concluded in accordance with a treaty or an act of Congress. However, presidents have sometimes reached executive agreements to achieve goals that would not find the support of two-thirds of the Senate. For example, after the outbreak of World War II, but before the Americans entered the conflict, President Franklin D. Roosevelt negotiated an executive agreement that gave the United Kingdom 50 obsolete destroyers in exchange for 99-year leases on some British naval bases in the Atlantic. The implementation of executive agreements increased considerably after 1939. Before 1940, the United States
