Not at all shocking. You have to understand the dynamic on the ground, to see why things are the way they are.
For example, AMISom are in it for the money. The day the donor countries stop funding AMISom, will be the day the wheels will come off this whole thing. Each AMISom soldier is costing the Europeans/American at least $2500 USD a month when includes all the amenities including salary. The Ugandas who have the largest contingent for example are raking in close to 20million dollars a month from this business venture.
For the SNA, again, it is all about self interest. The lady mentioned that, a business has to fork out close to 5,000 dollars on SNA manned routes. While the same business only forks out 1500 dollars to Alshabab controlled routes.
