It sounds like he is not "broken" any more. It is a hideous experience for anyone to have to recover from. Rwanda was probably the biggest single failure of humanity in my lifetime. We should have known beforehand that it was pointless sending in soldiers without any clear political decisions and without any real mandate to get the job done properly. "Great statesmen" often turn out to be mediocre politicians, whose soldiers have won battles for them. On the other hand, when the politicians fail, they can always pass the buck by crapping on the heads of their soldiers.
