Les avions sont des jouets intéressants mais n'ont aucune utilité militaire - Ferdinand Foch

I was convinced then—and my conviction has not since faltered—that the Treaty [of Versailles] then in the making, which I was not allowed to modify, was bad for the safety of France. Very bad. It was full of flaws, it was fundamentally wrong, and cannot fail one day to have the worst results. On the day when it is apparent in all its evil, when France perceives that her interests were improperly defended, she will rise in deep anger against those who so imperfectly handled that defence.

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 (épures), plans (schémas), etc. One only right solution imposes itself : namely, the application, varying according to circumstances, of fixed principles.

What you did was the greatest thing accomplished by any private soldier of all of the armies of Europe.
