Ah yes, inaccurate or misleading claims like [checks notes] easily verifiable campaigns of genocide by the Soviets?
And if you’d talked about their actual ethnic cleansing campaigns you’d have a point, or if it was a point worth bringing up at all in this context of deliberately helping the execution of Generalplan Ost.
You mean like how… the Soviets deliberately helped the execution of Generalplan Ost in assisting Nazi Germany to take massive amounts of Polish lebensraum with plentiful amounts of untermensch for them to massacre?
Are you arguing that Stalin was deliberately helping the plans for the Nazi conquest of the USSR by agreeing to partition a country the Nazis needed no help to conquer?
