I think that the lyrics are referring to how a Bosnian patriot started WWI, wanting freedom for his country. They are stating how they feel it was unfair of Bosnia to start the war. I am Bosnian and think it is ridiculous to blame all of Bosnia for just one citizen's actions upon Archduke Franz Ferdinand. The lyrics also say," Sarajevo changed my mind," most likely referring to the fact that Archduke Ferdinand was shit in Sarajevo, the capital of Bosnia and Herzegovina. Summarizing my comment, the lyrics are looking down on Bosnia in shame of WWI.
