Well, technical IS supporters (who did not participated in killings themself) are political imprisoned citizens as well.

The point is, that no matter what they did, they are all free now.

What are you trying to state? There's a small number of citizen IS supporters and they're now free, along with all others who showed opposition to the regime. Ok. So what? Please don't use a general understanding of the patterns in the region to extrapolate wild takes when you don't know the specifics of each country and their people. Syrians are not Afghans are not Libyans are not whatever, as much as the west would like to portray them.

"There's a small number of citizen IS supporters and they're now free"

If their numbers are so small, why was the IS a global problem then, a couple of years ago?

10 years ago. They were a problem because they used American cars, clothes, weapons and media.

Ah, so you claim they were a american controlled group?

While the US spend lots of effort on hunting them?

Keeping the flames high, to play firemen?

I don't think that there was a need of more flames, for that theory to be plausible. Occasionally some western weapons likely did found their ways towards IS as well, but they rather captured the bulk of it. Or do you have other sources?

Afghanistan is the obvious example, among many. Beyond that, American interventionism has fueled extremism in the region for decades. This is not a wild take, but one agreed upon by scholars.
