What what were the circumstances that we backed the Ethiopians in the first place? I'm sure they wouldn't have been there if it was as tranquil and the Garden of Eden. Musta been something bad going on there to send in the troops.
Yes, the US didn't like the Islamic Courts Union which had taken over most of Somalia. That's fine, but Somalia has now been occupied by a foreign invading army from Ethiopia for two years. That's extremely unpopular, and Somalis believe -- and are probably right about this -- that the Ethiopians are only there because the US has been arming them, paying them, proving them heavy air and logistical support, etc.
This is going to lead to one hell of a backlash, because the Ethiopians aren't going to want to die in Mogadishu forever.
