It was a great windfall for Albania, and a bitter loss for Serbia.

            A more worldly view of the outcome might be, Albania has an undereducated population largely addicted to the ancient superstition of Islam. Therefore they turn their backs on birth control and family planning, and have a runaway population growth.
            Sebia, on the other hand, has a more educated population, more willing to deal with reality and has had a more stable population growth for many years.
            For the world, then, I would say that NATO's adventure in Kosovo was a net loser and detrimental to the planet. It got Monica Lewinsky's picture off the front pages of the newspapers, at least for a while, but it was the wrong thing to do.
