Tbh Perun often just takes a report released by RUSI, ISW, or other war think tank and does some narration over it. On top of that, he often extrapolates from very small or noisy data.
His real talent is to find a bunch of these OSINT reports on a topic, combine them, and then apply his knowledge of economics and game theory and military history and theory to explain what it all means. As a PhD economist I can clearly tell he understands economics and has a talent for teaching it I only wish I did.
did you expect him to have access too, and release, classified data? What insights do you expect him to have over multi-billion-dollar intelligence and counter-intelligence efforts?
like, nearly all commentators, everywhere, are talking about OSINT releases from RUSI or CNA or whoever. and those are based on scraps from official UKR, NATO, RUS, etc. releases.
