Surely even Bismarck came to rue his role a peace maker at the Berlin Conference. True, European peace was brokered, but almost every participant, especially the Slavs cared less for peace than conquest, and forever blamed him and Germany for stopping the bloodletting. Bismarck should have followed his own advice and not become involved in the suicidal struggles of a bunch of “Sheep Stealers”.
LOL! Funny.
None of the major powers have ever gotten involved in the Balkans for any real reason that had anything to do with "the welfare of sheep-thieves" -- although that has often been the cover. It has always been about some major power becoming so full of themselves that they decide to expand their influence "eastward" (or if it's Russia, "westward") -- the most famous being the German "Drang Nach Osten" The Balkans is just the place that it happens, with one group played against the other over there. That's why the people hate each other in that region -- too many have groups been used as political tools of the Great Powers against each other there over the centuries.
