The west tried to keep ethiopia from sliding into a dysfunction at all cost but at this time no amount of support from anyone can help abiy suppress the several different popular resistances, in the older times factions were competing for the throne but now different ethnic groups are fighting for survival, a totally different scenario.
Fano fighters has the support of the 30 million amhara living in a mountainous highlands starting miles away from addisababa, so even if america sends boots on the ground they won't reverse the outcome from now on, and any other support is just a waste of time and resource, guerilla will keep fighting behind every tree and stone like that in vietnam no matter how much bombs you drop on them, and at that level bombs just backfire cuz they more likely kill more civilians than guerilla and hence more people join the geurilla.
And not to mention TPLF already evicted ENDF from tigray region and now engaging malicious acitivities with a foreign counties and agents in defiance of abiys orders.
Abiy acted as emerging ambitious, ruthless and dangerous king in east africa threatening almost everyone in the region but seems oromia jungles are gonna host him soon
