Museveni is already scheduled to get thousands of reinforcements and money for his troops in Somalia, paid for by the Americans and Europeans. There is plenty of military business for Uganda, which acts as a hit man and enforcer for neocolonialism in Africa.

Proxy control of Somalia by Ugandan forces would mean control of the Gulf of Aden, and some areas off the Indian Ocean.
