Moscow, 30th June, 1920
Dear Comrade Lenin,
Thanks to your kindness, we members of the Dutch delegation to the Second Congress of the Communist International were able to read your “Left-Wing” Communism – An Infantile Disorder prior to its publication in the European languages. In several places in the book you emphasise your disapproval of the part played by some members of the Communist Party of Holland in international politics.
We feel, nevertheless, that we must protest against your laying the responsibility for their actions on the Communist Party. This is highly inaccurate. Moreover, it is unjust, because these members of the Communist Party of Holland take little or no part in the Party’s current activities and are endeavouring, directly or indirectly, to give effect, in the Communist Party of Holland, to opposition slogans against which the Party and all its organs have waged, and continue to wage to this day, a most energetic struggle.
Fraternally yours,
DJ Wijnkoop
(on behalf of the Dutch delegation)
