Over at Moon of Alabama b real has an excellent writeup of the post electoral Coup in Kenya – Part 1. I recommend you go and read it. In addition to the article, the comments have continued all week, and contain a lot of valuable information and observations, including some from David Barouski who has covered that part of the continent in depth, and for some time. Included is Kibaki’s visit to Uganda, and his use of Ugandan troops against Kenyan citizens to hold his coup in power.
