People (groups) have their own reasons for backing or not backing Assad....doesn’t mean we’re collaborating
The majority of Syrian people are sunni muslim, the same as almost all al Qaeda/Muslim Brotherhood-linked groups. The Assad family are alawite muslim, which is an offshot of shi’a islam which is what you see mostly in Iran and some parts of Lebanon/Syria. The alawites are a minority in Syria and like Christians, Assyrians and other minority groups will be exterminated when the sunnis take over.
