DEI,your comments are wrong and petty!Why?
Because,all nations that were the part of Austro-Hungarian Empire were obliged to serve in the army(national service).Including Krajina and Bosnian Serbs!!!They were just a citizens of the state!
Truth to be told,when Austria invaded Serbia in 1914 ,many of them(Serbs) were in Austrian army!There are a solid historical data that massacres of the Serbian civilians in Machva(region of Serbia next to river Drina) were commited by Krajina Serbs!!!
Let me ,also,remind you,that when WWI begun,very few Bosnian Serbs deserted (Austrian army) and went to the Bosnian mountains to fight as a guerillas against Austrians!They were known as "Zeleni Kadar"(Green Kadre)!
To blame Croats for their participation (on Austria-Germany side)is wrong,they had n o choice!Just like thousands of Czechs,Slovacs,Magyars....
Using the same analogy,we should blame the Serbs for fighting for the Turks as Yanissaries!They had no choice!
BTW,Tropoljac,Russia didn`t attack Croatia!Croats were only a cannon fodder for the Imperial army!
Or you`re comment"we were attacked" is a wishfull thinking!Like "We belong..."No,friend,you don`t!No German is a friend or a partner to Croates,Slovenes....
Just a MASTER!Remember:We,Slavs, Don`t belong!
