BBC discussion (old) is HERE
but most of the commenters are far from the problem, and the most important comment is this one:
The brutal truth is that the UN, the tool of last resort, is so involved in Africa because there is no better way, assuming you view the map from the long-term, global angle. If there were a better way don't people think it might have been tried by now? Correspondents should not kid themselves into thinking that there is a magic cure for all the world's/continent's problems.
