There has been a consensus among Ethiopians for while now that there needs to be a regime change in Ethiopia, but not so much on how to bring about that change. The abrupt changes we have witnessed in Tunisia and Egypt in recent days seem to have given hope for Ethiopians that a similar change may be possible in Ethiopia in the near future.
It would be nice to have a relatively peaceful regime change in Ethiopia as have happened in Tunisia and Egypt. I doubt that will be the case though in Ethiopia as recent history of Ethiopian opposition groups is replete with disorganization and mistrust. I also question the wisdom of bringing about changes in a sudden way since that usually invites chaos and power vacuum.
Regardless, some kind of forced regime change in Ethiopia seems inevitable. If the Ethiopian people decide they had enough like their Tunisian and Egyptian counterparts, there is nothing the Woyane regime can do to prevent its own demise. The only question is whether or not the regime that will take over from the Woyane will be more accountable to the people.
