If Fano capture Addis Ababa then they will rule Ethiopia.It's possible, you never know, but the bad part starts after that... because what is bound to occur when they try to expand into other regions? without having allies in those regions, especially in Oromia? OLA's ranks will swell and then we may see a major war. remember, when tplf, despite having the superior military, expanded outside of its region during the war against mengistu, they had to build alliances throughout the country prior to conquering the capital.
At no time should Oromos allow FANO to take over Addis.
Its like the same way they allowed TPLF to take over Addis Ababa in the 90s.
Because 100% they will copy the same model TPLF used and oromos will fight for another 100 years this time these peasant amhara will be more brutal than even menelik.
