To this second, I still can't explain what the hell is happening. There have been many Sade civil wars, but even the most stupid of them had a reason.
I have no idea why Abdirashiid Janan of Dollow is attacking Beled-Xaawo. I mean I know WHY (Ethiopia is using him), but I can't rationalize why he would do it.
Like Ximan said, Beled-Xaawo is considerably bigger and diverse whereas Dollow is smaller and primarily one sub-clan.
This guy is playing with fire. If this is tribalized, those multiple clans can raze Dollow to the ground in one second and take out all the members of Janan's subclan.
No one wants to make this tribal or even spread the fire. People are just shocked and weirded out this guy just won't go back.
