Here is a conflict map. I think it gives obvious clues about who is rebelling and what areas ENDF care the most about controlling
Looks like ENDF has firm conrol over AddisAbaba. Conflict in Benishangul-Gomuz, Tigray, and WesternOromia
Abiy appears to be safe from rebellion in TewehedoOromoia zones. He is not even facing stiff resistance in the land of the fiercely antiAmhara Caruusa zone. EasternOromia conflict is probably tribal conflicts between ethnically confused linguistically Oromoized Somaali fighting each other in Hararga
Overall I dont think Tigray matters much to PP. TPLF occupied Badme until Abiy and Eritrea evicted them so I suspect Ethiopia did not rely on trade routes to Tigray. What OLA is doing and even BeniShangul-Gomuz matter more to Xabashistan.
Not trying to take Walqayit indicates backdoor deal that gives them Badme but not Walqayit.
TPLF has powerful allies but no one can bring back TPLF rule. Everyone is waiting on what happens between Oromo rebels and Abiy. An Oromia rebellion emboldens the peripheral states nations like Soomali region to assert themselves. ENDF would have to focus on controlling Qoti heartland before they can control periphery
