It's just a miracle!
Isaias has been preparing for the last 22 years to fight with Ethiopia and Abiy has also spent billion of dollars for the war and has trained hundreds of thousands of soliders. How Tigray defeated the combined forces of Abiy and Isaias cannot be explained and I give Glory to God and appreciate the Tigrayan people, the leadership of the TPLF, the militery leaders of TDF and it's fighters and each and every Tigrayan participated in the defensive war!
