The reason why Nabar iyo Naxdin are so eager to bring Amisom to Galmudug is not to fight against the remaining pockets of Al Shabaab. The goal is to have Ethiopian soldiers in every part of the country because of the special relationship Farmajo has with Abiy.
Ethiopian soldiers, whether they are under the banner of Amisom or under the Ethiopian flag, follow Farmajo's orders even when they are illegal and violate Amisom's mandate as demonstrated in Baydhabo this past December. Amisom losing their EU funding and ending their mission is no problem for Farmajo with a friend like Abiy.

- Puntland is too well established and autonomous. We are older than the FGS and have full control of our borders.
 
- They would not have international support because it is clear to everyone that there is no need for Amisom in this region and there has never been a need.
