I don't think Serbs scoped for a polish independance in the start of WW1.Their aim was the dissolution of Austrohungarian empire foremost and then the political entities which would arise were unknown to them.
sothern, hardly that we can say that every Serbian peasent was aware of possible development of situation in case of Austro-Hungarian dissolution. But, inteligentsia, urban population and circles in connection with crown were aware of situation and, they were proud of Serbian role as piedmont of Slavic world.
any help that Serbs could received was wellcomed. There was a lot of mujaheedines in Srebrenica that opperated under cover of EU and NATO. EU and NATO were aware of mujaheedine massacres over Serbs but anyway didn`t react. That`s why governmant of Bosnian Serbs needed to sent general Ratko Maldic in the area.
Its not only that Greaks took part on Serbian side. Some Russian, Lusatian, Polish, Bulgarian and Ukrainian mercenaries/volunteers also were involved on the behalf of Serbs that were captured by mujaheedines in Srebrenica area.
all people that was involved in crimes should be sent to jail. Here, all crimes that were eventualy commited on Serbian side were individual crimes without ideological background (only pro-Turkish Bosnian Muslims and pro-German Croatian side had/have developed genocidal ideology for extermination of Serbs).
But, what must be remembered in history is that EU, NATO and Islamic league created all that chaos in former Yugoslavia. They wanted war, they innitiated war, they profited on it.
