If ur not aware of already Al Shabaab are already getting dismantled, there's alot of Al shabaab fighters turning against each other and with in 1yr theyll be gone, these foreign troops are supported by the international community and there's billions being poured in too but since Somalia is stable now they'll all be leaving by 2019, don't get mad at me bro, it's not my fault the TPLF are throwing u out in the land fill and burying u in garbage,this is rich coming from someone who has over 5 countries ravaging his country. Why don't you take back your country from Shabab? You guys control less then 10% of your own country while foreigners control the rest lol.
Plus Ethiopia's politics isn't so cut and dry. It has more or less has to do with party affiliation and less to do with ethnicity. The top security positions might be controlled by tigrayan but most other fields are held by other Ethiopians. Most of the developmental work is also happening in the Oromo region.
