France and Weapons of Mass Destruction - History

History

France was one of the nuclear pioneers, going back to the work of Marie Curie. Curie’s last assistant Bertrand Goldschmidt became the father of the French Bomb. This was discontinued after the war because of the instability of the Fourth Republic and the lack of finance available. During the Second World War Goldschmidt invented the now-standard method for extracting plutonium while working as part of the British/Canadian team participating in the Manhattan Project. But after the Liberation in 1945, France had to start again almost from scratch. Nevertheless, the first French reactor went critical in 1948 and small amounts of plutonium were extracted in 1949. There was no formal commitment to a nuclear weapons program at that time, although plans were made to build reactors for the large scale production of plutonium.

However, in the 1950s a civilian nuclear research program was started, a byproduct of which would be plutonium. In 1956 a secret Committee for the Military Applications of Atomic Energy was formed and a development program for delivery vehicles was started. The intervention of the United States in the Suez Crisis that year is credited with convincing France that it needed to accelerate its own nuclear weapons program to remain a global power. In 1957, soon after Suez and the resulting diplomatic tension with both the USSR and the United States, French president René Coty decided on the creation of the C.S.E.M. in the then French Sahara, a new nuclear tests facility replacing the C.I.E.E.S. With the return of Charles de Gaulle to the presidency of France in the midst of the May 1958 crisis, the final decisions to build an atomic bomb were taken, and a successful test took place in 1960. Since then France has developed and maintained its own nuclear deterrent, one that would defend France even if the United States refused to risk its own cities by assisting Western Europe in a nuclear war.

In 1956 the French agreed to secretly build the Dimona nuclear reactor in Israel and soon after agreed to construct a reprocessing plant for the extraction of plutonium at the site. The following year Euratom was created, and under cover of the peaceful use of nuclear power the French signed deals with Germany and Italy to work together on nuclear weapons development. The West German Chancellor Konrad Adenauer told his cabinet that he "wanted to achieve, through EURATOM, as quickly as possible, the chance of producing our own nuclear weapons". The idea was short-lived. In 1958 de Gaulle became President and Germany and Italy were excluded.

France developed its nuclear and thermonuclear bombs without outside assistance. The United States, however, began providing technical assistance in the early 1970s through the 1980s. The aid was secret, unlike the relationship with the British nuclear program. The Nixon administration, unlike previous presidencies, did not oppose its allies' possession of atomic weapons and believed that the Soviets would find having multiple nuclear-armed Western opponents more difficult. Because the Atomic Energy Act of 1946 prohibited sharing information on nuclear weapon design, a method known as "negative guidance" or "Twenty Questions" was used; French scientists described to their American counterparts their research, and were told whether they were correct. Areas in which the French received help included MIRV, radiation hardening, missile design, intelligence on Soviet anti-missile defenses, and advanced computer technology. Because the French program attracted "the best brains" of the nation, the Americans benefited from French research as well. The relationship also improved the two nations' military ties; despite its departure from NATO's command structure in 1966, France developed two separate nuclear targeting plans, one "national" for the Force de Frappe's role as a solely French deterrent, and one coordinated with NATO.

France is understood to have tested neutron or enhanced radiation bombs in the past, apparently leading the field with an early test of the technology in 1967 and an 'actual' neutron bomb in 1980.
