You need look no farther than the Ottoman importation of Muzzies to the region.
You are correct, but it is currently more complicated than that.
The Orthodox Christians, Croatian Catholics, and the Muslims have been at war a long time. There have been atrocities that would repulse the most resistant soldier to the point it is a blood feud.
The atrocities that the Muslims did with the SS during WWII were inhuman. The things they are accused to having done in Kosovo are possibly worse. (organ harvesting)
The news that was reported in Bosnia and later in Kosovo by the press, was largely trumped up against the Serbs.
I still do not understand why the international media and our government took the sides that they did.
I know that Milosevic was a commie, but the Serb people were much more in tune with the west.
My point was, that although I prefer the Serb people to the others in the Balkans, there are no good guys there. It is long past that.
