Wishful thinking. Who's going to be securing K5 that stretches from Djibouti to the Kenya border? You think the Somalis in K5 are different than the ones who been fighting for a quarter century in Somalia? In the event of a civil war, Somalis will have each clan securing their strongholds and fighting among themselves for disputed lands until they're subjugated again by whoever wins in the highlands.
No wishful thinking here. Liyuu police are already doing well keeping Oromo at bay and securing the borders. They operate all over the region. Also Right now there is no single clan wars in the region and no disputed land what the hell are you on about? everyone has full control of their regions and seem to be getting along just fine. An Issa in Shinile and a Garre in Liban all know where they belong and who they are up against.
One of the problems we might face is leadership but we're probably ok on that too since a lot of Barre veterans have gone back and currently work for the DDSI. Other than that we have a very big advantage over the Oromo because Somalia has many ports and we can ask for support and backup from any country. Importing weapons through these ports changes the game because everyone else is landlocked unless Eritrea suddenly becomes friends with the Ethiopians.
The other problem is allies. The west have always had the backs of Habesha so that's the only big issue we might face.
Some form of unity + some form of an army + ports + some form of leadership = Biggest opportunity of secession since 1977. No subjugation will take place unless the west interferes and keeps the Highlanders in power.
