What about the Balkans? After the fall of the USSR, that region could have blown up into a huge criss-cross of wars. From what I've read, damn near every nation in the Balkans has a grudge against at least one other Balkan nation; Albania/Yugoslavia, Yugoslavia/Hungary, Hungary/Romania, Greece/Turkey, Bulgaria/Turkey, Yugoslavia/all the ethnic groups inside it's borders.... get all these going at once, and you have a major land war....
