Having 2 systems also allows for comparison between both of them. Whichever system works out better dictates the future of the countryThis is precisely what HSM is doing right now yet FMS will still fight him over that. There is literally no satisfying them.
Listen I'll be blunt. Federalism in Somalia is a total joke and needs to be dismantled ASAP. The only exception is Puntland and Somaliland since they have been around for a long time and proven themselves capable of being functional. When has Galmudug, Hirshabelle, Southwest and Jubaland ever been functional? Since day one its nothing but chimpouts in those places so centralism is the only path left for central and southern Somalia.
