SNM started what USC finished man. SNM and its Ethiopian backing gave people the confidence to take down Barre.
Barre saw this renewed confidence and thought the way to quash it was to send the harshest message possible.
Regardless of SNM, USC or whatever group you hold responsible.
You can't defend the collective punshiment and targetting of Isaaq civilians by the government. That is the reason we are in this mess because people are sympathetic to the plights of innocents from all clans. You can disagree with SNM while also condeming human rights abuses and the heinous crimes that occured.
