You don't corner a cat. You give them an escape route. Otherwise they have nothing to lose. You cannot win against these tribes or nation in their god forsaken territories. You go in quickly and come out. Fighting people who are already in mortal combat with desertification is not wise. You just join their long list of enemies - poverty, climate change, disease, name. It's survival for the fittest. And worse when they have cover like Mountains or forests...that make air power irrelevant.
This is US in afgan or Kenya in Somalia (a war that cannot be won).
US is telling Ethiopia proud Amharas to negotiate but they cannot imagine being beaten by Tigray.
I thought that war was over and won(by Ethiopia). The Horn seems to be cursed with these tribals that will fight, even suicidally, just for pride.
