Left Wing Communism, an Infantile Disorder- New Translation - Little Lenin Library Volume 201920

"Left-Wing" Communism: An Infantile Disorder is a work by Vladimir Lenin attacking assorted critics of the Bolsheviks who claimed positions to their left. Most of these critics were proponents of ideologies later described as left communism. The book was written in 1920 and published in Russian, German, English and French later in the year. […] Lenin points out that the Russian Revolution has considerable international significance, and criticises the leaders of the Second International, including Karl Kautsky, for failing to appreciate this. […] Lenin asserts that in a war against the bourgeoisie, "iron discipline" is an "essential condition". He then describes the circumstances which led the Bolsheviks to this conclusion in their success at taking state power in Russia. -- Fron Wikipedia...
