The questions surrounding the involvement of foreign actors are interesting meanly because of the timing. It’s interesting that Iran see a vague of mass protests right after the utter failure of the nuclear talks and when they are admittedly very close to getting the bomb. Plenty of foreign powers therefore have an interest into seeing the current regime fall down and have historically never been above giving a gentle push in the right direction. It wouldn’t in any way make the reasons of the protests illegitimate however.

Now, I don’t really understand why you bring Al Qaeda and the Uyghurs to the mix. That needlessly muddies your point.
