You were not alive around that time, the people who were and lead rebel movement have already said what you are asking.List the pros and cons.
I would say yes! We should have left that homie alone.
Here's mine and before anyone asks, I am Darod but not Marehan.
pros
strong government
top 2/3 strongest military in Africa.
stable country
better equipped to deal with famine and droughts because of the government institutions being functional
Ethiopia and Kenya would't be toying with us today.
Our marine fisheries woudn't be stolen
no amison
no alshabab
we could have dug the oil/gas by now.
last but not least, if Somalia's government hadn't collapsed, we could have gotten somali galbeed in 1991 when Eritrea also declared independence after the Ehio civil war.
cons
He killed a lot of people, specially in the north, but we lost millions more after he was gone so this is still a pro in my book.
he let his clan run wild: I can accept this if the country remained strong and stable.
he wanted to keep the kursi no matter what: again i can accept this.
We lost so much by chimping out in 1991 and made zero gains.
Let's be objective and keep qabiil emotions out of this discussion.
the question is not even about leaving MSB alone it is should have gone in for the kill after he already wanted to leave power as he said he no longer desired to be President. But the rebel leaders wanted to go in for the kill because they feared his return would get them executed which they probably would have.
The rebels didn't just fight against a dictator by the way, they fought against civilians and each other but more importantly they could not come to an agreement with each other even with MSB out of the picture that is what actually destroyed the nation.
