Covering the war in Bosnia, I found American diplomats ready to rat out the local Mafias behind Serb aggression.  They were much less forthcoming about the Mafiosi fighting on the Bosniak and Croatian sides and how criminal connections among all 3 groups kept the war profitably going. Harvard scholar Danilo Mandic's new book Gangsters and Other Statesmen says this wasn't just a Balkan phenomenon. Mobsters can start and stop wars everywhere from Mali to Georgia and from Libya to Kosovo.
