Struggle is everywhere, without struggle no life, and if we want to go on living, we must be ready for further struggles. - Otto von Bismarck

Politics is the art of the possible.

In all these questions [of economics] I pay as little regard to science as I do in any other judgment of organic institutions. Our surgery has made splendid progress during the last two thousand years; but medical science has made no progress in regard to the internal conditions of the body, into which the human eye cannot see, and here we stand face to face with the same riddles as before. So it is with the organic formation of States. In this respect the abstract doctrines of science do not influence me: I judge according to the experience which we have. I see that the countries which protect themselves prosper, that the countries which are open are declining, and that great and powerful England, that strong combatant, who, after strengthening her muscles, entered the market and said: “Who will contest with me? I am ready for any one,” is gradually going back to protective duties, and will in a few years adopt them so far as is necessary to preserving at least the English market.

The Balkans aren't worth the life of a single Pomeranian grenadier.
