[7] The weapons are part of the country's Force de dissuasion, developed in the late 1950s and 1960s to give France the ability to distance itself from NATO while having a means of nuclear deterrence under sovereign control.
[9] During the Second World War Bertrand Goldschmidt invented the now-standard method for extracting plutonium while working as part of the British/Canadian team participating in the Manhattan Project.
In December of 1954, Prime Minister Pierre Mendes-France met with his cabinet, authorizing the foundation of a program with the goal of developing French nuclear weapons.
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.
[18] The Chancellor of West Germany 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 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 U.S. 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 defences, and advanced computer technology.
Although he recommended against Polynesia because of its distance from France and lack of a large airport, Ailleret stated that Algeria should be chosen "provisionally", likely due in part to the Algerian War.
The explosion took place at 40 km from the military base at Hammoudia near Reggane, which is the last town on the Tanezrouft Track heading south across the Sahara to Mali, and 700 km/435 mi.
[29] Gerboise Rouge (5kt), the third atomic bomb, half as powerful as Little Boy, exploded on 27 December 1960, provoking protests from Japan, USSR, Egypt, Morocco, Nigeria and Ghana.
[30] After the independence of Algeria on 5 July 1962, following the 19 March 1962 Evian agreements, the French military moved the test site to another location in the Algerian Sahara, around 150 km north of Tamnarasset, near the village of In Eker.
As many as 100 additional personnel, including officials, soldiers and Algerian workers were exposed to lower levels of radiation, estimated at about 50 mSv, when the radioactive cloud produced by the blast passed over the command post, due to an unexpected change in wind direction.
In 2006, Bruno Barrillot, specialist of nuclear tests, measured 93 microsieverts by hour of gamma ray at the site, equivalent to 1% of the official admissible yearly dose.
[33] Despite its initial choice of Algeria for nuclear tests, the French government decided to build Faa'a International Airport in Tahiti, spending much more money and resources than would be justified by the official explanation of tourism.
Many French overseas islands were studied, as well as performing underground tests in the Alps, Pyrenees, or Corsica; however, engineers found problems with most of the possible sites in metropolitan France.
[47] Along with the Polynesian NGO Moruroa e tatou, the AVEN announced on 27 November 2002 that it would depose a complaint against X (unknown) for involuntary homicide and putting someone’s life in danger.
One hundred fifty thousand civilians, without taking into account the local population, are estimated to have been on the location of nuclear tests, in Algeria or in French Polynesia.
[49] Several French veterans and African and Polynesian campaign groups have waged court cases and public relations struggles demanding government reparations.
During World War I, France, not Germany as commonly believed, was actually the first nation to use chemical weapons though this was notably a nonlethal tear gas attack (xylyl bromide) carried out in August 1914 against invading German troops.
In time, the more potent phosgene replaced chlorine in use by armies on the Western Front, including France, leading to massive casualties on both sides of the conflict however the effects were mitigated by development of protective clothing and masks as the war progressed.
During the invasion of France, German forces captured a French biological research facility and purportedly found plans to use potato beetles against Germany.
[55] The testing of chemical weapons occurred at B2-Namous, Algeria, an uninhabited desert proving ground located 100 kilometers (62 mi) east of the Moroccan border, but other sites also existed.
However, at a conference in Paris in 1989, France declared that it was no longer in possession of chemical weaponry but maintained the manufacturing capacity to readily produce such weapons if deemed necessary.
