“Diplomats know that, in the scales which ensure that balance of power, European or otherwise, which we call peace, good feeling, fine speeches, earnest entreaties weigh very little; and that the heavy weight, the true determinant consists in something else, in the possibility which the adversary enjoys, if he is strong enough, or does not enjoy, of satisfying a desire in exchange for something in return.” – Marcel Proust, The Guermantes Way (trans. Moncrieff and Kilmartin)
