"Tigray" is neither a nation, nor a historical place.
It is a potpourri of several nationalities that have come to be arbitrarily called "Tigray" in the closing years of the 19th century.
The government of Abiy and Issayas would be foolish if they try to play cat-n-mouse with TPLF. TPLF's prerequisite to conduct guerilla warfare are coming along nicely.
But this brings with it a good opportunity for the two governments. That of seeing a very simple solution to the whole "Tigray" problem.
And that is the nationalities of "Tigray" hitherto unknown and unseen by the blind eyes of the federal government.
This in turn gives the real Tegaru the opportunity to see the futility of "Tigray" and come to the fold of "Agazay". And that would be a win-win situation for everybody involved.
