Abiy problem with Tigray started when he claim the TPLF/EPRDF 27 years were dark!
Abiy was persuaded to call the 27 years of TPLF/EPRDF rule as dark years during his visit to USA to please his core supporters( Isaias , archaic unitary Ethiopia dreamers and Derg officials). That was the greatest error of Abiy which damaged the trust between himself and TPLF and brought Ethiopia to the mess we are experiencing.
