The whole term "moderation" and "moderate" are useless terms. He ruled Idlib with an iron fist and smashed any group and anyone who got in his way. HTS ran a hisba or religious police. Its detainees were treated reprehensibly although not on the scale as in Assad's prisons. 

The idea that the West can liberalize any Islamist group is completely ignorant and has been discredited everytime it's been tried.

So let's stop kidding ourselves. And stop using weasel words like "moderation."
