Masha Allah, nicely put, very eloquent, the issue of secession, they will make stories, true or fictional, grievances, real or perceived, or even fabrication, exaggeration, to further their agenda,
You have understood and identified their issue very well.
Many people, from South, fail to grasp this or many times are even persuaded or fell for this misinformation by separatist, or sometimes too preoccupied with Mogadishu politics, greed, or incompetence, BUT with Goojacade, SSC issue, Awdal ,and now the Somali sea, it is becoming very clear, these guys are dangerous to Somali people.
There are only few options left.
Let go of secessionist enclave, secessionists clearly understand now, SSC, will never be part of them, so as Maakhir who have now cemented with PL, Also remove Awdal. Habro territory only can form a country, it is big enough.
Make a real deal , focus and pay attention, give them a deal they cannot refuse, this may not work, as Somali Presidents are not very reliable partners too, very big trust issue, for example, they meant to get some share of the resources coming from ICAO, but instead of trust building, Mogadishu took everything, this is multiplied many times over, offer a good deal, Canada style
Tigray , Tamil tigers, Spain, Catalonia, etc, defeat them, this is very likely scenario,
Possible implosions, very likely too, as the Somalilanders are doing big injustices to themselves too
