It's called replacing the ethnic people (in this case Somalis) by new habitants (here Oromo in north and Bantu in south) which happened before in history like Turkstan which was annexed by China and Soviet Union and disppeared now. North America. Kurdistan which divided by 4 countries, France divided Tuareg lands by 5 countries......etcMeanwhile, Somalia is importing thousands of unskilled Kenyans and Ugandans to work in cities like Mogadishu and Kismayu.
Something doesn't add up.
