If I were being inducted into the Russian Army after the phenomenal "success" of Putin's Ukrainian smash-&-grab, you could bet your ass I wouldn't go sober, either.
For a nation that learned first-hand the lessons taught by the Blitzkreig, it's become fairly evident that at least the current crop of Russian flag officers hasn't internalized those lesons. Zhukov - to say nothing of Joe Stalin himself - would have started shooting subordinates who hadn't achieved complete air superiority 6 to 8 months into a fight like this, with the numeric advantages the Russians have already brought to the field. Hell, the Ukrainians still have many of their military airfields intact and unmolested. Back in the cold war days, the generals on our side of the Fulda Gap expected to have use of such fixed, unmovable targets as air bases for no more than 24 hours after the "festivities" kicked off.
The stagnant nature of Russia's attempted armed robbery of the Ukraine doesn't bode well. In this case, time is on the side of the Ukrainian defenders.
