Do you know how Barre Hiiraale was tricked by Abdiwali aka Xiirane to attack Kismaayo, the 3 day war that ended with his defeat, hundreds of deaths and exhile to Goobweyne to die out slowly.
Farmaajo approach to JL is no different to Hiirshabelle, SWS, Galmudug, believe it or not he is not interested in Kismaayo, he united the factions in Gedo while they were all individually working for Madoobe, it was them who decided to get Madoobes fingers out of Gedo, not Farmaajo, it was also them that demanded Farmaajo pay them directly their share in JL funding. Madoobe is pissed with Farmaajo only because of Kenya, he don't care about Farmaajo's relation to Gedo, he don't even care about Gedo kicking out his water boys, or losing some hard cash to Gedo.
Madoobe is a business man, he wants Kismaayo and his bloodline to have a stake there, he is also open to working with Farmaajo it is his kenyan handlers that are pushing zero sum game.
And then there are crazy Cagdheers from kililka who love to rape and murder, they think they can take over the land like they thought they could in Beletweyne and Hargayssa, they will lose ultimately. BTW I use to support Madoobe until he picked sides and betted on Kenya keeping him there. We still leave the door open for him.
