Not that you really care either way.... Exactly what does person with your double standards consider sufficient atrocities inflicted on Serbs to warrant the right to defend themselves? Not that I really care for an answer, so if your schedule leaves you pressed for a response, don't bother.
However, this doesn't excuse the brutality unleashed upon the Croatians by the Serbs in any way.
That's one opinion. Another one identifies the Croats as having started a war, as in WWII, and leaves them alone to fight it out to the end. If you're truly appalled by either the Croatian genocide of WWII or their efforts to start a war in 1991, you would appreciate that the targets of their genocide have the right to defend themselves.
If you had any sense of common decency, you would certainly not come on here to defend treasonous Balkan terrorists for starting a war and then having the great moral courage to go running to the US and Germany for help.
