Because of another primitive rats from North, Neftegna, the country would likely heading to ethnic conflicts. As I predicted before the following wars are inevitable:
1/ Gallas vs Nefxegna
2/ TPLF vs Nefxegna
3/ Beneshangul , Galla and TPLF vs Neftegna
4/ Somali vs Afar vs Galla
5/ Ethiopia vs Backwarded Eritrea
6/ I don't think there would be a war between Ethiopia vs Sudan, but each country would look to support oppositions rebels.
In the meantime, the country will shake up with famine, disease , corruption, robbery, etc.
Solution:
1/ Immediate discussion with all respective parties
2/ stop the war in Tigray
3/ Create a transition gov that prepares for democratic election
