Most of that enhancement has been flushed out at this point.
No serious student of the Bolshevik Revolution, for instance, would contend today that the Romanovs were murdered without Lenin's knowledge or consent (as was once claimed in the Soviet Union). And Khrushchev's denouncement of Stalin effectively (but not entirely - just as with Trump, there are some that will never see) ended his cult of personality.
There are many other myths that have arisen about the early leaders of the Communist movement (and not just Russians, Mao in China, Ho Chi Minh in Viet Nam, Fidel in Cuba, etc.). But I submit that most of those "enhancements" have been categorically refuted at this stage.
Not by the useful idiots, perhaps, but by the intelligentsia and professional revolutionaries. ;0)
