I can’t predict any interactions among Alewites, Sunnis, and Shiites since I don’t know much about any of them.... but simply as a matter of general political psychology, I doubt that any outside efforts to make Syrian Alewites feel more insecure and more humiliated in the Muslim world is going to make them more amenable to moderation.
Just as Hitler often felt driven to prove he was more “German” (as an Austrian originally) than most Germans, and as Stalin felt driven to prove his “Russian” character (even though he was from Georgia), Assad and his ilk may well respond to insecurity about their identity as Muslims by being more extremist and violent, not less so.
The Shiites are roughly 30% of the Middle East Muslim population. Iran’s goal is to convert Sunnis to Shiism. It does it by becoming the most powerful Muslim nation that defies America and Israel and even attacks them directly or via stooges such as Hezbollah. Iranian wackos also have an end times scenario in mind
Alewites are idiots with no oil riches. Their numbers are so tiny, as you know.
