>Perhaps as part of the humanitarian effort we could send in advisors from the Balkans to teach living together peacefully and letting bygones be bygones.
Perfect example.
Balkans were fine whenever left alone. We had 45 years of peace. But then everybody and their aunt saw a chance to spread their influence - the wahhabis, the Vatican (btw, "holy see" is "sacred stool" in Serbian), the EU, the US, CIS/Russia, Iran, Albania... did I forget anyone?
Of course, when the local leaders started negotiating for a rehash of the Federation, they were already promised this or that by who knows who, and were helped in every centrifugal way. No matter that 90% of the people didn't want that, 10% is enough to start a war. And the weapons started pouring in.
