Ninyahow MOD was dead, Ogadenkii USC baay naga raaceen and even Saado was signing Land cruiser

Maybe yall shouldn't have conspired to kick us out of kismayo.

MSB messed up when he did not step down, but if he did, who'd have replaced him?

By the late 80s, there was SSDF, SNM, USC, SPM and SNF, I don't see how those groups would support a replacement that wasn't from their respective qabiils, afterall they picked up arms because they felt their particular clans were marginalized.
Now, the bigger mistake came after he was ousted. If he was the problem, the war should have ended after he was kicked out but that didnt happen. Daroods were haunted down like animals in xamar and killed. They in return did the same thing in the areas they controlled. isaqs retreated to their region. Another 25 years passed and clan warfare never ended. I actually think a civil war was inevitable at some point.
he was partially at fault but not entirely.
