[ Dzyuba, Ivan: Internationalism or Russification. Edited by M. Davies, Weidenfeld and Nicolson, London 1968. p. 67–68]
On the basis of this article,
Ivan Dziuba, a Ukrainian-born Soviet philologist and a staunch Leninist, criticized Isakov strongly in his book ''Internationalism or Russification'' (1968) for repeating "what was written by the propagandists of tsarist times and in their falsified history textbooks," an attitude "which looked on the whole surrounding world whether it was in the way of Russia or not, whether it satisfied the appetites of tsarism or not." Dziuba used Isakov as an example of how tsarist Russia was identified completely with the contemporary USSR and how Great Russian chauvinism had surpassed "the Communist class approach" with "a pitiable
Shulgin-type interpretation of the grandiose class battle of the proletariat, of the grandiose drama of universal history!"
