So Puntland and Somaliland only have Tigre military advisers and instructors
The North region of Somalia is the most reactionairy region in Somalia. While one half (Northwest) wants the dismemberment of Somalia for pure selfish clan-reasons the other half (Norteast) wants to hand over the sovereignity of Somalia to Ethiopia for pure selfish clan-reasons.
In all ocupations throughout history not an entire country was occupied but the strategic locations. Thus in Somalia its Banadir (Both Shabbele regions), Hiiraan and Bay and Bakool. These regions also happen to be the economical and political power centre´s.
The other regions do not need direct occupation by military units as they are in no position to endanger the occupational country´s goals, matter of fact they are already occupied politically as they have Ethiopian ''ambassadors'' and officials residing in Hargeisa and Garowe respectively.
So the only difference between the parts that are occupied militarily and the others that are occupied politically is that the former parts are still opposed to the occupational force thus requiring a large military occupation to persuade the people to accept it, while in the latter parts the people do no need persuasion as they have already accepted to accommodate Ethiopia's wishes in their political plans (political occupation).
The Northern reactionary entities must be transformed from their current reactionairy, anti-National Interest of Somalia or they must be dissolved.
