Erm.. I don't recall saying anything about anything being 'over'; I just said that the ICU had left Mogadishu. They have.
They don't, but for rather different reasons than you believe, I suspect. If they had significant forces their best chances against the Ethiopians would be in Mogadishu. Laudable though it would be if they had left just to prevent civilian casualties, I don't believe a word of it. They had far more men, more heavy weapons and organisation than the warlords who gave the Americans and Pakistanis such a hard time there. It's the 'had' that's the problem, once the perception of the ICU as 'winners' faded, their 'support' in the form of militia rapidly faded with it and they became just a 'faction' again in Mogadishu, among many. They can fight a guerilla war, certainly, but the question is who will fight it for them? How many Somalis believe in the cause rather than just what is in their own short-term self-interest? No doubt suitable recruits can be imported, but they really have no more business fighting in Somalia than Ethiopia does.
Torture is always terrible, but how do you know what he was being tortured for?
