what are the qabils that live around the capitalMany African countries don't fully control their territory and have pockets of insurgents across their countries. However, each of these countries has a functioning government with full control of the capital city. As long as you have those two things, you aren't a failed state.
Somalia could have neither because the communities living around the capital were the most violent people in the world and detest any semblance of civilization. If it were not for these people, Somalia's civil war would have lasted only a few years before a new government was formed; this is exactly what happened in Ethiopia. Somalia wasn't destroyed by the U.S., it was destroyed by you know who.
