What they suggest is "one-click" nuclear war. Qui vit sans folie n'est pas si sage qu'il croit.
Whether they be russians at Stalingrad or french at Dien Bien Phu or british in bombed London, those old guys "knew" in their guts what a war was about... And they thought (at least in France) that with the army getting more and more technical, some weird guy would one day think of it just as a "game" of power and economics...
