Its entirely possible the Russian High Command actually believes its own obfuscations.

After the end of WWII, US authorities acquired the Imperial Japanese Navy's after-action report on the Battle of Midway in 1942. Reading the report, it is impossible to arrive at the conclusion that the Japanese lost! In their eyes, the results were, at best, inconclusive. We know today that this engagement was one of the most decisive in history. In a matter of hours, the Japanese war effort transformed from a victorious rampage against the Allies to a complete turning point and a slow but painful retreat. the IJN lost 4 carriers, all their aircraft and their best pilots. They never recovered.

No one can accuse Japanese naval planners of incompetence, they were brilliant, but reading this report should demonstrate how even the best military minds are capable of deluding themselves; or at least, of covering their asses so effectively they are incapable of recognizing, much less correcting, their mistakes.
