 The French army officers' uprising was due to a perceived second betrayal by the government, the first having been Indochina (1947–1954).In some aspects the Dien Bien Phu garrison was sacrificed with no metropolitan support, order was given to commanding officer General de Castries to "let the affair die of its own, in serenity" (""laissez mourir l'affaire d'elle même en sérénité"").The opposition of the UNEF student trade-union to the participation of conscripts in the war led to a secession in May 1960, with the creation of the "Fédération des étudiants nationalistes" (FEN, Federation of Nationalist Students) around Dominique Venner, a former member of Jeune Nation and of MP-13, François d'Orcival and Alain de Benoist, who would theorize in the 1980s the "New Right" movement.
