concept in this manner: "The nuclear and classical levels tied to each other, essentially with classic atomic weapons, brings to the latter the stability it lacks and returns to the former the elemental risk of instability that it needs in order to continue its role as the great stabilizer." Beaufre is saying that nuclear and conventional deterrence are "Siamese twins" because the instability the conventional mode provokes makes nuclear deterrence necessary, precisely in order to obtain stability. In sum, true deterrence is obtained only through nuclear deterrence. Quotes "We suffered from an illness which is not peculiar to the French - the illness of having been victorious." "The collapse of the French Army is the most important event of the 20th century." "Throughout the entire course of history, warfare is always changing." "No explanation for the current strategic situation is satisfactory without a definition of the nuclear situation; no definition of the nuclear situation is possible without knowledge of the laws that rule deterrence." "The game of strategy can, like music, be played in two keys. The major key is direct strategy, in which force is the essential factor. The minor key is indirect strategy, in which force recedes into the background and its place is taken by psychology and planning." "A South African policy which does not disarm (the opposition to apartheid from the Third World)... by some well conceived reforms and by a big information effort, risks allowing a hostile atmosphere to build up and to harden." "Victory is a very dangerous opportunity."
