The real fight will be between Somalia and Somaliland, not Al Shabab who are Ethiopian minions.
I disagree, Farmaajo is silly to pick a fight right now with S/land, you will only cause more hatred at this moment in time and it benefits none of us, especially when he has far bigger enemies like the corrupt elites up in P/land that overthrew him before that already threatened him and the Ethiopian stooge Sakiin.
It will be absolutely suicidal if he opens up the S/land front, I hope smart people advise him, he doesn't need to do anything in S/land other then block UAE deal using the opposition as cover who are all opposed to this, that's without becoming visible.
His focus should be consolidating power, his enemies will be Sakiin, Gaas and Ethiopia, he should focus on building the army, establishing the institutions, and limit the influence of all these powers or replace them, in fact the love of the people will grow more and they themselves will replace them, P/land will be the toughest to deal with, but HSM has done most of the damage.
He doesn't need to do anything regarding S/land other then block dumb deals using the opposition, it will collapse within itself soon, Siilaanyo's own sub-clan are threatening him, if Farmaajo gets involved, he gives an opportunity to the secessionist, why would you do this? and open an unnecessary front for yourself while so many are open currently?
One of the reasons I supported Shariif was precisely because of this temperament issue with Farmaajo, I love him, but I feared he would do just what you wrote and either be overthrown or a motion being passed against him, Sakiin is already against him and so is Gaas, with S/land you have 3 states, that's enough to overthrow him with a motion and keep in mind J/land can switch anytime as well.
Because he is a populist candidate, the entire country will go to hell and the people will give up, you will give victory to Ethiopia and the secessionist and everything worked for will be destroyed, never ever go to war even politically unless you take care of all the loose ends and know 100% you will not only win but win the hearts of the people as well in that place.
Once Xamar alone is booming and basic stuff is done, the people themselves will overthrow those incompetent leaders, this is the thing that makes me very nervous about Farmaajo and the key will be who he appoints as advisers.
