Obviously the government was involved. They are vehemently opposed to the formation of Jubaland. Hassan Sheekh can't exactly order 5000 SNA soldiers from Lower Shabeelle to march on banging war drums. The government has to subtly make do with whatever loyal factions they have in the region. That was a tiny clan militia that caused uproar to test the waters. Larger pro-gov clans were just watching. Gaaljecel, Shiikhaal, Biimaal etc etc let alone the heavily armed Marehan and Gedo.
The govts policy towards kismayo has failed, the minister has left the town for fear or bc he wasn't able to enter it again, now things are at zero. I know what is wrong with them, its because they don't want to clash with kenya. I mean what is the point of destroying ahmed madoobe and appointing him again!
