It's only "yesterday's war" as far as COIN is concerned. Against state actors, maneuver is still the order of the day. Even with counterinsurgency, moving infantry with helicopters is a force multiplier.
It's true that asymmetric warfare is the most likely face of warfare in the future, but countries with standing armies still remain a greater threat to the United States.
When, not if, the US gets in a fight with another country, it'll be the typical blitzkrieg again. So no, it's not "yesterday's war".
Its true that maneuver warfare is not completely dead. But don't forget the same things were said about maneuver warfare and the impending conflict with the Soviets during the cold war. And blitzgreig was yesterdays war.
Only by the narrowest of definitions. The US modus operandi with armoured warfare could be straight out of the German High Command's playbook. I strongly suspect that Guderian, Rommel and Manstein would be completely at home with US non-COIN doctrine.
Also, what's this about the Soviet Union? I'm having trouble parsing that sentence.
