The basis for the "noise" coming from Mogadishu is that Hawiye are being sidelined in the Jubbaland initiative.
Clearly the HAG is behind a lot of this false propaganda, although its disappointing to see the "president" parroting such bellicose statements.
The premise that the Jubbaland rejectionists are operating under, is that Hawiye are present in large numbers and have a veto.
Now I don`t claim to know the demographic of the region, beyond a very simple understanding.
However, I have been told by people familiar with the region, that Hawiye (Geeljecal, Sheikhaal, Hawadle), are present in only 3 districts with a majority in maybe 2.
I have heard nobody claiming they want to displace or dispossess Hawiye, on the contary, Jubbaland initiative is based on the guaranteed rights and representation of all the people.
Here is the Somali administrative map.
Feel free to fill in the demographics.
Thanks
