I refreshed my memory about the way the Socialist Federal Republic of Yugoslavia broke up. I will not insult you with a trite precis, but I see the common themes of unemployment/hopelessness (with the cheerful IMF gnomes providing their usual contribution,) mob hysterical conversion of ordinary neighbors into demons needing to be cleansed and psychopaths creating mob action for idle hands. As Thomas says, at a *minimum* there needs to be a capable acceptable government whenever organization falls or is brought down, otherwise the modern experience is that the psychopaths step in.
What do you think is the solution for the problem you describe? What chance that the Republic can reassemble into a coherent entity with more scale? If not possible, then what is the solution and what are the idle youths doing today?
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
