>>8564220From a pur epragmatic standpoint:
>enter the country as liberators>pretend to give the oppressed peoples of the SU autonomy once the war is over - also treat them humanely>destroy the SU from the inside while destroying the Red Army>prepare for prolonged conflict just in case, in conjunction with aforementioned good relations with the Ukrainians and other oppressed Soviet peoples, mobilize them and cause major defections across the USSR>by 1943, with the Soviet Union falling apart, take the oil, gas and everything else valuable>inform the people you just conquered that it was all a ruse to make the SU fall apart faster, but give them a humane option to move to the east, behind the Urals, where they can start a new Slavic nation (of course this is after the Red Army and the SU's ability to make war have been wiped out)
