When soviet union colapsed 30milion rusian found them selves outside their borders new rusia. That exactly what will hapen ethiopia colapses imo
no it won't If It collapsed, it would be amazing for us because as the Somalis say
"gaal baa god igu dhacayee gadhwaynta ii keena" which roughly translates into "we would f*ck shit up and take revenge on them".
There's no way any habashi would come to Somalia. We would reiginite old rebel groups like the ONLF and secure the borders, have a chat with xamar for funds and weapons, and lobby for independence.
