These developments marked the beginning of a period of “détente” in line with a general tendency among Americans to favor a lower profile in world affairs after the Vietnam War, which finally ended in 1975 with the last withdrawal of U.S. personnel. While improvements in relations with the Soviet Union and the People’s Republic of China signaled a possible thaw in the Cold War, they did not lead to general improvement in the international climate. The international economy experienced considerable instability, leading to a significant modification of the international financial system in place since the end of World War II.
During the Nixon Administration, international scientific, technological, and environmental issues grew in prominence. In October 1973, Congress passed legislation creating the Bureau of Oceans and International Environments and Scientific Affairs (OES), to handle environmental issues, weather, oceans, Antarctic affairs, atmosphere, fisheries, wildlife conservation, health, and population matters. The Department had difficulty filling the new Assistant Secretary position until January 1975, when the former Atomic Energy Commissioner, Dixie Lee Ray, took the job. However, she resigned six months later claiming that OES was not playing a significant policy role.
Although Secretary Rogers still had broad responsibility for foreign policy, including Europe, the Middle East, Africa, Latin America, and international organizations, the Department of State resented its exclusion from key policy decisions, and the Secretary continually fought to make his views known.
