These quotes are worthless, because they have no source citations. Such a citation might resemble the following: "V.I. Lenin, Collected Works, Progress Publishing House; Moscow, 1958; Vol. 23, p. 15." The Soviet Government published many editions of Lenin's Collected works, in a wide range of languages. Any one of those editions can be cited as a source. Such a publication proves - for most - that Lenin uttered the words in question. If You can find contemporary newspaper articles, that reprinted the full text of a speech - in which Lenin expressed a view that You quote - that newspaper should be cited as, e.g., Pravda, 23 March 1918, p. 6. These source citations proves the words in question actually were spoken. Until you have - and affix beneath each quotation - one or more source citations, remove these quotations.
