Were Krushchev, Brezhnev and their Vanyas from Tambov Jewish ?
Were 22 millions party members, 42 millions of komsomoltsy all Jews ?
They just changed the name and methods 1917 in order to have more efficiency in mass killings, ethnic cleansings, pacifications etc.
Actually in my opinion word 'Soviet' is accurate. You stick only to such statistics and periods that fits to your wishes.
Leadership of Bolshevik revolution was 'very Jewish'. Lenin was not Jewish, neither a Russian. Himself did not identify with any nation. So how could they be representative to Russian imperial ambitions?
