No. Without Mogadishu, all other regions fail. The burden must fall on Mogadishu. Everything is concentrated in Mogadishu, therefore its unfair to put an undue burden on Puntland. Its xasid. It's like expecting Somaliland to rejoin Somalia while it's own shit isn't in order. What's the incentive?
The problem is that the government can't lead because its duties and responsibilities are not clear, and the powers among federal institutions are merky at best and that is why we have a stalemate.
Just some of the basic questions:
What areas can does the federal government have exutive authority over?
Who decided the PM or President? What happens in a gridlock?
How should natural ressources be shared? How about taxes, can States make their own?
What are the powers of the supreme court?
Nothing will get done without a completed constitution, but I suppose if that is in your interest that makes it okay.
