I don't know.

It seems like they are ready to read everything into what happened.

People who pay a lot of attention to the Turkish military and people who pay a lot of attention to Gulen seem to think it's an unnatural marriage. That doesn't mean that it couldn't be a CIA coup on two rails and people that think that these two sides cooperating is unlikely have said it's possible that Gulen has quietly made in roads with the military over the years under the radar. The military definitely hated Gulen when he was in the government.

I'm sure there is some seed of truth somewhere in this video but I also think these people are so eager to paint a narrative that they'd be a great way to feed conspiracy propaganda for the benefit of any party that's anti U.S. or NATO.
