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. In analyzing an international agreement for its domestic application, U.S. courts have the ultimate power to interpret the importance of the agreement.163 In general, the Supreme Court has stated that its purpose in interpreting an agreement is to recognize the intent of the contracting nations.164 The interpretation process begins with a review of the text of the [memorandum] and context. in which written words are used. 165 While an agreement stipulates that it must be concluded in several languages, the Supreme Court has analyzed language versions to help understand the terms of the agreement.166 The Court also considers the broader „purpose and purpose“ of an international agreement.167 In some cases, the Supreme Court has cautioned extratextual documents, such as the development of history. .168 the views of the other contracting states.168,169 and practices after the ratification of other nations.170 The Court warned against this practice. 171 U.S. post-war diplomacy was strongly influenced by the executive agreements reached in Cairo, Tehran, Yalta and Potsdam.485 For a time, the formal treaty – the signing of the United Nations Charter and adherence to multinational defence pacts – such as NATO, SEATO, CENTRO and the same – was restored. , but quickly, the executive agreement, in addition to the contractual agreement or only by presidential initiative, has once again become the main instrument of U.S. foreign policy, so that in the 1960s it turned out that the nation was somehow required to protect itself from more than half of the world`s countries.486 The turmoil in Congress was nothing more significant than the passage of a „sense of the meaning of the Senate resolution“48 In the United States.48 , executive agreements are concluded exclusively by the President of the United States.
