Be assured, we shall not go to Canossa, either bodily or spiritually. - Otto von Bismarck

Die Politik ist die Lehre vom Möglichen.

The German who is still free from all Slav or Celtic alloy has a distinctive character and vies with all his equals. When he is allied with other races, provided he has the necessary patience and endurance he always succeeds in becoming, the chief, the directing will, as the husband must be in a household. I have no desire to offend the Slavs, but it is very necessary to recognise that their character has much of the feminine in it: they have charm, intelligence, artifice, address, and often the Germans appear heavy and clumsy beside them. But we always carry the day, and that is why I would like to say to you: when you are doing business with your Slav rivals, even at moments of the most violent anger and in the most critical situations, always retain the profound conviction, the most profound but secret conviction, that you are fundamentally their superiors, and that you always will be so.

Be polite; write diplomatically; even in a declaration of war one observes the rules of politeness.
