Not only did they control the Romanian oil fields, Russia was the 2nd largest oil producer in the world, 2nd only to the US. And they still hadn't developed their western oil fields.How, I thought at the end of the war the USSR occupied the Romanian oil fields?We would have cut the fuel supply to the Soviet Air Force and all those big lumbering Russian tanks and artillery would have been nothing more than target practice for the Army AirForce.
