They are called the "Ooga-Dageen people" or the Higlanders as they are called from within Ethiopia. Anyway, it is a political suicide fo a member country to lay claim to take on another's recognized land. Unless by force and about in your face approach.

Why the dreaded O is there? they are the only people who are available to continue this alone. In fact, the rest of the Somali groups (clans) went against the "struggle" by surrendering all their ambitions to the "enemy" or friend as they call them.
