One outcome of the Potsdam Conference that had an enduring legacy was the agreement on the creation of the United Nations Organization.
The goal of the new organization was to serve as an international body to resolve international disputes among its members and thereby reduce the risks of another major war.
Despite the growing entrenchment of differences concerning Eastern Europe, both the United States and the Soviet Union signed the founding statement at the San Francisco Conference of June 1945.
General Assembly
The new organization's Charter provided for a General Assembly which represented all members of the United Nations.
Security Council
The real decision-making powers were entrusted to the Security Council. The victorious Allied powers ensured their international supremacy through the creation of Permanent Membership on the Security Council.
The UN had several advantages over its predecessor, the League of Nations.
In reality, the growing divergence between the Soviet Union and the western powers made effective decision making, within the United Nations, extremely difficult.
