NOT Bush's fault
Your mass killings were instituted approximately 10 years ago. In 10 years' time, you, YOU have done nothing to improve the situation; indeed, you -- and your counterparts in the other tribe -- have continued to exacerbate matters, via your actions, your speech, and your bizarrely stupid governmental policies.
1) Why is any nation anywhere somehow responsible to commit huge amounts of resources to keep two primitive, and more importantly, primitively tribal cultures from killing each other?
2) You -- or at least your nation -- could stop this slaughter in short order by abandoning your ridiculous notions of tribalism and reaching (effectively) an internal non-aggression pact with your fellow citizens of your nation of the opposing tribe, yet you don't. You don't even try. Would civilised peoples not be, would the world at large not be, net bottom line and no 'human rights' BS (which concept eludes BOTH your tribes), well better off by letting you lot mutually slaughter each other into extinction or near-extinction?
Absent hard evidence to the contrary, and given your nation's history since independence, I would tend to say, very simply, have a nice trip to hell.
No? You mean genocide is no big deal so long as a compassionate hypocrite is in office?
