Your mad, Croats initiated conflict. Their allies enabled it.
Well, you goes deeper into genesis. Who are Croats? They are Catholic Serbs. And why are they Croats? Its Vatican`s and Germanic project. Then in WW2 they moved (while 300 elite ustashe terrorists were trained directly by Vatican in Italy and when started war they moved to back then Kingdom of Yugoslavia to form nazi ustashe) on Orthodox Serbs and remaining Catholic Serbs and killed in genocide more then 1 mil. Serbs.
See?
Then again, when EU and NATO wanted to destroy Yugoslavia and Serbs, they used Croats. Sure, and local Muslims in Bosnia that were Islamized Serbs. Some still consider themselves to be Islamized Serbs.
Just like Serbian blackhand initiated ww1, while Russia enabled it.
No.
AH annexed Bosnia and Herzegovina which is ethnic Serbian land. Serbs are natives there. Then AH committed genocide on native Serbs. Serbs resisted. Gavrilo Princip is result of it. Then AH declared war on Serbia and attacked. Russia and then Entente powers entered war on the side of Serbia. Started WW1.
So, AH started WW1. By all and every means.
