I find myself underwhelmed.

This coup attempt, if these details are even vaguely correct, was amateurish at best. I think if the Montenegrans were making this up whole cloth as leverage in internal politics, then the plot would be a lot more 'threatening.' I could devise better. In fact, when playing D&D, I did.

Yet if we accept the story as true, what does Russia have to do with it? Some Serbs have felt a kinship with Russia for centuries now. Why would we be surprised that some Serbs chose to go and "see the elephant" by fighting for a Pro-Russian militia? In my own Civil War, a number of our Irish volunteers in the Army of the Potomac spoke only Gaelic when they arrived. Foreign born volunteers are scarcely rare. The Brits did not blame us when some of them went home and joined the Fenians in 1867.

This is hardly conclusive evidence for a Russian backed plot for Serb domination of the Balkans. If there were such a plot hatched by Russia -- led by ex KGB folk -- I suspect it would be better funded, organized, planned, and led then this shocking cock-up.
