Haven't you noticed, the peace levels in abgaal parts of mogadishu, primarily northern mogadishu since the 90's and now? the war has been in southern mogadishu at all times where the galgaduud hawiye dominate who have no elders among them in the town or respected person to control them. I studied why and it's because they left galgaduud and settled hamar not going under 'imam abgaal' and if they did, mogadishu would've been very different outcome today. So you basically have these lost hawiyes running as ghetto niggas in the southern parts of the town.
The best answer is to put all power into imaam abgaal to control the whole city as their traditional ruler and have all their politicians report to him while the galgaduud hawiye report to their ancient kingdom puntland. Now aborigines will have a home under two kings one majerten and one abgaal, somalia civil war is essentially over.
