"A four years' war and the subsequent peace have divided Europe into two sections, the winners and the losers. The winners have even less reason to make war than in 1914. Peace will never be threatened by them. Does that hold true also of the losers? Have they resigned themselves to their defeat and the moral and material losses it entails? Who can say? Germany, for instance, was for centuries moulded in character and instincts by Prussia, who regarded war as a lucrative national industry; she will experience much difficulty in changing her mentality and outlook."

“If France has a firm hold of the Rhine, she may be at rest, for she can be sure of reparations and security; without the Rhine she has neither. All that may be offered or given in exchange is valueless, illusory, empty. That is the position I took up immediately. We must have the Rhine line; we want nothing more and will take nothing less.”

“Germany is about to join . It will be alleged that she conforms in spirit to that of the League. If you hope that she will desire to maintain the frontiers forced on her, which she has never acknowledged in her heart, and which, bluntly speaking, she loathes and yearns to destroy—if you can hope that, you must have more than your share of naïveté.”

“To be disciplined does not mean being silent, abstaining, or doing only what one thinks one may undertake without risk; it is not the art of eluding responsibility; it means acting in compliance with orders received, and therefore finding in one's own mind, by effort and reflection, the possibility to carry out such orders. It also means finding in one's own will the energy to face the risks involved in execution.”

“This absence of similarity among military questions naturally brings out the inability of memory to solve them; also the sterility of invariable forms, such as figures, geometrical drawings , plans , etc. One only right solution imposes itself : namely, the application, varying according to circumstances, of fixed principles.”

“This is not a peace. It is an armistice for 20 years.”
