According to the 1976 TPLF Manifesto, the map of Tigray will look like this if Woyanne succeeds. Note that the Tigray border stretches to Red Sea. That may explain:
1) why Tigrean elites — even those who hate Meles — have soft spots in their hearts for Woyanne, and
2) they are obsessed with Eritrea, currently the only power in the Horn of Africa region that is capable of preventing the manifesto from becoming a reality.
