Come sxb, let's have an open dialogue on this, I swear I harbor biases towards anyone, I'm just trying to be realistic about Somalia as a whole
In the political landscape of Somalia, federalism only venerates clan identity and strengths nepotism. Each state having their armies would embolden them to undermine the Government for their own interest, GM, HS, SWS, JL, PL having their own agendas only weakens Somalia as a whole.
Federalism works for Puntland due to favorable clan demographics, but to the rest of the states, it is a complete disaster, the south is a melting pot, there are too many powerful clans vying of supremacy.
The federal states cannot develop fast enough, 3/5 are flat out broke, and the extremely modest budgets for the rest of the states are supported by resources inherited from the prior Somali state, such as the port of Bossaso for Puntland which was built in the '80s....under a centralized state.
Puntland is only against centralized rule as being directly ruled from Xamar gives Hawiye a political leg up, they don't dislike the system at all but just where it's being applied from, which is a very understandable concern, but let's not pretend federalism is the solution because it is absolutely NOT.
