Whether fake or not, it is definitely adding some perspectives I didn't see up until now. For example, I have not considered the possibility of Kadyrov position not being very stable if he loses (or already lost) his soldiers in something that was supposed to be short and glorious war.

Same with how does Russia keep their Syria effort supplied when their logistics in Ukraine are already stretched.

So this is definitely written by some analyst, but who knows if from FSB.
