At the time, an independent deterrent force was not in the cards: the idea was that the possession of nuclear weapons would have restored political and military equality between Paris, London and Washington. No one in Paris had forgotten France's exclusion from the Quebec Agreements (1943), which had laid the foundations for American-British nuclear cooperation, even though French scientists had been at the origin of the first works on the military applications of the atom (the work of Frédéric Joliot in the 1930s); or its absence from the conferences of Yalta and Potsdam, which had seen the fate of the continent decided in the absence of Paris.3 Moreover, some political leaders wanted France to have a military capability that clearly differentiated it from Germany.4 - Theny, the limits of the commitment of the United States towards its allies, which Paris noted on the occasion of the crisis of Diên Biên Phu (March- May 1954).
