I see the first guy on the list says Germany. I think that is not just simplistic but also uninformed and pretty idiotic.
Serbia, with our without civil government knowledge was training terrorists. These terrorists killed the Austrian Crown Prince. From that point Austria was committed to punishing Serbia and likely incorporating it into their empire.
From that point it was Russia who wanted more influence in the region, France who wanted revenge on Germany, and Britain who felt Germany was mustering in on their turf.
Germany was boneheaded when it came to preventing the war but they sure were one of the lesser players in starting hostilities.
The trouble with the history of WW I is that everyone still wants to believe all the nonsensical propaganda put out by their side.
