Well, the Soviet Union's aim is to force Germany into neutrality, so that they can then go for the Middle East without retaliation. Somehow, I doubt that this stacks up very well.
First of, the win condition of Germany peaceing out is hard to swallow. The Soviets will have grabbed Iceland, and the Red Army reaches the Rhine--what next? Some cases suggest that as the Soviet Union advances on the Rhine NATO resorts to tactical nuclear weapons, which will probably lead to everything getting launched, or the Soviet Union tries to secure things like Bonn on the far side of the Rhine and offers to hold on the French Border, France decides to Frappe the Soviet Union, nukes fly, 90% of the world dies.
Even if Germany does opt to peace out, the SECOND MOVE is going to be the end of the line. The Soviet move to grab additional oil supplies in the Middle East, AFTER A SHOOTING WAR WITH THE WEST must lead to a nuclear confrontation. This is all happening after the United States has cut off all shipments of grain to the Soviet Union, so the Soviet People are starving...
Suffice it to say, the Soviet Union winning German neutrality is pushing the West enough; going after the oil, as was originally intended with the level of tensions in the world is probably going to lead to a nuclear exchange. The Soviets will have killed tens of thousands of Americans--a stinging defeat, but also a sign that the Soviet Union would DARE to start a shooting war. The cold war goes into a deep freeze, and I'd suspect that when the Second Campaign starts, the Soviet Union finds the West is not nearly as weakened politically as they dreamed...
