Gary Farber of Amygdala has covered Darfur as well as any blogger out there - and he has done so consistently. NATO in Darfur describes what (still) going on, as well as recent moves by the USA and even by specific politicians within it to deal with the situation. It's a fine piece, lots of links and information on current developments.
Short background: the African Union force has been ineffectual, with no real mandate to stop the Muslim Arab Janjaweed. The genocide is less intense because the blacks have largely been driven out or killed, but it continues. China continues to block any serious action on the diplomatic front due to its oil interests. All the Arab League states want us to focus on their created Palestinian diversion rather than actual genocide. Covering for the Sudanese and Janjaweed is par for the course in that crowd. Europe, which does indeed have the troops and equipment to handle this easily if it wished (heck, Spain and Italy alone could have done so), does nothing as usual. The UN is happy to take cash, some of which will get to the refugees, but not of course to do anything that might actually stop the rapes, killing, etc.
There are many states with the resources to stop this other than the USA, and had they wished it this crisis would have been over long ago.
Darfur: "The Global Test" in action. How do you like it so far?
