i I have seen that quote before from several independent source and it varies slightly as you might expect; from a Russian to English translation? For instance I think one said it was in November 1918 at a central executive committee meeting. However it often cited in sources you might not have 100% confidence in and they lack a more precise source eg date and primary document etc. And it isn’t in the Lenin archive; which won’t be complete anyway. This is one of them Lenin made a statement in the Russian Cabinet in October of 1918, in which he said: "I am often accused of making this revolution with German money. I never denied it and do not now. But, on the other hand, I will make the same revolution in Germany with Russian money." (See Nesta Webster's "The Surrender of An Empire," pages 76-77.) not read that book to check to see if it has source
