it would indeed be expected that the arabs in the area would be annoyed by a kurdish military presence, as these were the nazis that supported the jihadist groups in the first place. the kurds have indeed put a lot of people in jail, for the reason that they are jihadist terrorists. they operate large prisons of isis collaborators.
the narrative present in the cnn article is something like german citizens complaining that the allied occupation is rounding up all of the nazis and putting them in jail. why can't they leave germany to govern itself in peace? what has germany ever done to it's neighbours, anyways? right?
if you understand american foreign policy, and how it uses media to confuse people and manufacture consent, this kind of propaganda shouldn't be surprising to you. but i still find this article to be galling and unnerving in it's contempt for truth and decency.
in fact, if you understand the history of the region, you know that the arabs are recent migrants into it, and that they were resettled by the ottoman turks during a period known as the armenian genocide. the indigenous peoples of the area were assyrians, armenians and kurds, many of them christians. the turks tried to wipe them out and replace them with arabs because they weren't muslim enough or muslim at all. by acting as though anybody should give a fuck about these colonizing arab groups, that slaughtered the indigenous people of this region to enforce their religion on them, a process which isis was essentially continuing, the tone of the article is fully upholding the validity of that historical wrong. the ongoing genocide of the indigenous peoples of the upper euphrates-tigris valleys and their replacement by muslim arabs is one of the most brutal issues of our time and something that the west has been fully complicit in.
i've been critical of obama, as many leftists were, but his policy in upper mesopotamia is one of the few things he got right. the americans finally stood up to the systemic genocide carried out by muslims on the indigenous population. but trump seemed non-committal and biden completely reversed the policy. now, here we are - the united states is openly aligned with isis and complicit in the ongoing genocide (which is about to ramp up) and cnn is posting propaganda about it to convince you into supporting it.
