If you actually read my post you'll see that I chose the word "spark" rather than "cause".

Apology accepted :)

You can't argue with true believers. The Balkans has always been a problem -- I always liked Bismarck's comments that (1) the Balkans weren't worth the bones of a single Pommeranian grenadier, and (2) if there were another major European war, it would be caused by "some damned fool thing in the Balkans". He may also be the source of the term Balkan "powderkeg" (Pulverfass in German), but I suspect it's older. Central and Western Europeans have not had much nice to say about the Balkans (other than the coast for resorts) going back almost all the way to the height of the Roman Empire.
