BBC NEWS | Africa | Sudan atrocities strain US relations

*Go figure*

US says what's happening in Sudan is genocide (which theoratically obliges them to intervene to stop the massacre) and is calling for another ad-hoc tribunal to deal with the crimes.

The UN on the other hand says there's sufficient evidence of crimes against humanity but stop short of calling it genocide, instead they figure to use the ICC to prosecute individuals instead (although how they figure ever to get them into the court without some form of intervention is beyond me)
