Is that relevant?
Are you trying to say that these al-Qaeda/HTS, this Takfiri Salafi Islam is a good thing for Syria?
The point here is that most (if not close to all) of these "foreign fighters" are actually foreign to Syria. They are goons and brain washed monkeys of western Intel, through Saudi funded mosques in the west. Loved by Tel Aviv and welcome in Davos (what does that tell you).
You would probable say the same about Libya.
It is a very tough job to find "good" rulers, but if they don't even serve the interest of their "own" country (but that of others) you are looking into bigger problems than a dictatorship.
