TPLF has lost and the blame game is going around for the devastating lose. No, it was not me, it was that, this body. You are accountable, specially if you had a leadership position during the war. You were the commander in chief of your force. Debretsion can never blame the failures to somebody else.
My advice to them is to draw a lesson, never try to use force, monopoly of violence lies with the government, which is the interim government in this case.
