What is your proposed solution? The reason war lords control the region is to exploit rare earths. Why not create some kind of mediatory influence to reinforce the UN? I'm not pretending to have all the answers here.
Your comment is abhorrently condescending and shallow. Yes, you have highlighted a historic atrocity and grievance of the region - why is this a reason why the west shouldn't try to help these people? In your mind, are the people of the DRC "beyond" help? That's an awfully charged and deconstructive opinion my friend.
