What is the fastest way to conquer the Soviet Union? Usually it takes a lot of time to conquer them and drains lots of resources. I think that the best strategy is to conquer Yugoslavia, Bulgaria and Turkey to be able to deploy landing crafts directly at the Black Sea. Then I puppet Iraq, Saudi Arabia, Persia and Romania to get around 25% of the world's oil. After that I begin to build my navy for the Baltic and Black Sea. Finally, I DoW the USSR and do lots of sea shore invasions at their undefended coasts. This frees me of slow heavy fight and makes encirclement easier. Eventually I would use Paratroops to get their VP's that are undefended in the Urals by making airport after airport landing.
