Nazi Germany intended to destroy Russia permanently, irrespective of whether it was capitalist, communist or tsarist. Adolf Hitler's Lebensraum policy, expressed in Mein Kampf, was to dispossess the Russian inhabitants – as was to happen with other Slavs in Poland and most of Eastern Europe- and to either expel most of them beyond the Ural mountains or to exterminate them by various means. Under Generalplan Ost, German colonial settlement was to be encouraged.
