“Rus withdrawal from Kharkov has duped the the Ukies into giving up their advantageous artillery spotter positions in tall buidings there”
You mean like the sneaky Russian plan to lose thousands of troops, including the front line paratroopers as well as hundreds of tanks, armed personnel carriers and the flag ship Moskva, all in a “feint”??
No, the Russians lost kharkiv and they are retreating haphazardly.
The theories these pro Russians come up with are just silly. Never heard such an explanation before.
The only logical translation would be, the Russians were getting hammered by artillery, so they withdrew out of range.
