Do you feel that the habashas have lost control over Ethiopia? Their number has been decreasing and with time the Oromo will take full power with the backing of small ethnic groups.
What about the civil war that took about 600k Tigray lives, will that make any changes to Ethiopia, will they finally abandon this quest to conquer the horn? They are already losing control to rule Ethiopia adding the horn, will make them a minority.
I remember reading that they forced the Amhara language and tried making the rest of the country into habashas but that has ended up failing. They now trying nationalism.
