Well, we cooperate with them too?West supports HTS as well. How do you think they managed to stay in their corner of Syria while ISIS was being bombed to oblivion? How did US did multiple anti ISIS ops without touching HTS? They cooperate.
Of course it is. It's a fundamentalist holdout with nowhere to go with millions of malnourished refugees under its rule. Turkey did silently act against HTS multiple times in the last year.
As I said, if HTS is a threat to Turkish national security, that's another matter. I just think we should look at them realistically and not through ideological lenses.
