The following list includes the top ten international treaties after the Second World War. These treaties consist of a formal and binding written agreement between actors in international law, most of whom are sovereign states and international organizations. This list consists of the most important and influential international treaties of the post-war period, as well as other ideas on their purpose and importance. The main concern of the American treaties after the Second World War was security cooperation in a post-war climate marked by ideological conflicts with the Soviet Union, the bipolarization of the world between these two powers, the destruction of colonial empires and the emergence of nearly ninety new nations, economic inequality and dependence on nuclear weapons as a deterrent. As a result, the United States has not been able to pursue its traditional (moderate and reserved) contractual policy. Indeed, since 1945, it has entered into more contracts (without agreement) than any other nation, and almost all have been new type. These included assistance agreements, participation in the United Nations, peace agreements, alliances, deterrence treaties and treaties that address a wide range of issues that traditionally: human rights, ecology, environment and resources, global warming, the prohibition of chemical weapons and other weapons of mass destruction, access to space and future use of space. , copyright and intellectual property protection, as well as biotechnology and human cloning. The Charter of the United Nations was created as a way to save “future generations from the scourge of war.” This is the result of the inability of the League of Nations to resolve the conflicts that led to the Second World War. Now, as early as 1941, the Allies have made a proposal that has created a new international body for peacekeeping in the post-war world.
The idea of the United Nations began to be articulated in August 1941, when U.S. President Franklin D. Roosevelt and British Prime Minister Winston Churchill signed the Atlantic Charter, which proposed a set of principles of international cooperation for the maintenance of peace and security. This term was first used officially on January 1, 1942, when representatives of 26 allied nations met in Washington D.C and signed the United Nations Declaration, which endorsed the Atlantic Charter and presented the United Allied War Objectives. The United Nations Conference on the International Organization, convened in San Francisco on 25 April 1945, met with 50 represented nations. Three months later, when Germany visited, the final Charter of the United Nations was unanimously adopted by delegates. It was signed on June 26; The Charter, which included a preamble and 19 chapters, divided into 111 articles, called on the United Nations to maintain international peace and security, promote social progress and improve living standards, strengthen international law and promote the extension of human rights. The main organs of the United Nations, as defined in the Charter, were: the Secretariat, the General Assembly, the Security Council, the Economic and Social Council, the International Court of Justice and the Guardianship Council. The three governments took note of discussions in recent weeks in London between representatives of the United Kingdom, the United States, the Soviet Union and France to reach agreement on the methods of trial of major war criminals whose crimes do not present a particular geographical location after the Moscow Declaration of October 1943. The three governments reaffirm their intention to bring justice quickly and safely to these criminals. They hope that the London negotiations will lead to a quick agreement to that end, and they believe it is very important that the trial of these great criminals begins as soon as possible.
