Initially, Roosevelt envisioned the new postwar international organization would be formed several years after the war. Later, he came to view creating the United Nations as the most important goal for the entire war effort.For Roosevelt, "establishing the United nations organization was the overarching strategic goal, the absolute first priority." His vision for the organization consisted of three branches: an executive branch with the Big Four, an enforcement branch composed of the same four great powers acting as the Four Policemen or Four Sheriffs, and an international assembly representing other nations.
