On 5 December 1963, General André Beaufre, former Chief of the General Staff of the Supreme Headquarters, Allied Powers in Europe (SHAPE) and French representative to the permanent group of the North Atlantic Treaty Organisation (NATO) in Washington until 1961, publishes an article in the French daily newspaper Le Monde in which he reflects on the concept of deterrence in nuclear strategy. In 1963, General Beaufre pens a work entitled ‘Introduction to strategy’, which offers a philosophical and overall view of military strategy in the 20th century.
