Send your soldiers to kill, burn, kidnap Gurages. Make it official. Stop arming neibhoring communities to kill, burn, kidnap Gurages and claim their lands and steal their shops, coffee, cash and cattle. Stop using Hadya, Qebena, Mareqo and Shene Oromo.
Declare an official war on Gurage as you did on Tigrey, Amara, Oromo, etc. This will help Gurage to hope that the war will end one day.
Please!!!
