Who's the Real Hidden Player in Somalia?

Well, it is said that the Ethiopian troops will withdraw from Somalia since they drove what is called the Union of Islamic Forces out of power. It is said too that the American war crafts bombed some locations in Somalia suspected to be hidden places for members of al-Qaeda involved in the explosive attacks against the American Embassies in Eastern Africa. With all this said about the issue, the American administration is failed to represent any evidences about the presence of any of those groups in Somalia.
