It may happen, it may not. From what I have observed so far- the Syrian opposition despite their divisions-seem to have put a lot of thought into post take over. That’s why life continues as normal in places like Aleppo and Hama. I know you want them to fail so you can say “life was better off with muh Assad, look I told you so”, but painting a gloomy outlook based on a few videos is a bit over the top. There will also be more incentives for Syrian opposition groups and remnants of the regime to have a political discourse by countries like Qatar, Turkey and the EU. Somalia was never seen as that important.
My only concern would be the reaction of the jihadi coalition within Jolanis people if they deen him as straying to far to the path of a secular Arab nationalistic state. We might see some infighting and splits once that path is crossed. It will probably look more like Libya in the recent years not exactly Muqdisho 91.
