International law means nothing.

I don't understand your interpretation of what's happening in Zimbabwe as essentially different from what happened in the past 10 years in the Balkans. Croat and Bosnian Muslim troops from the beginning targetted unarmed Serb farmers for extermination. Unlike the Zimbabwe whites however, the vast majority of Serbs had been farming that land long before the United States was ever formed as a country.
