Gurage doesn't have a history or culture of taking other people's lands without purchase. When Gurages own farm lands or urban lands in Oromo, Sidama, Hadiya, etc, they purchase the lands. Free see port on the Red Sea by forcefully taking it from Afars of Eritrea doesn't fit in the moral scope of the Gurage culture.
Amara and Oromo culture is very suitable for such endeavor.
