Yesterday, I stumbled across this interesting description of how the Communist International started to go wrong: "By the early 1920s the revolutionary wave which had swept Europe had ebbed. In these circumstances Zinoviev turned away from seeking to build independent working class strength, as Trotsky continually argued was the way forward, and looked instead to alliances with other elements. This had disastrous results."
The author? The SWP's Chris Bambery, in his introduction to 'A History of Communism in Britain' by Pearce and Woodhouse. Any resemblence to the SWP's current strategy with Respect is entirely co-incidental, of course.
Someone famous once said that those who do not learn from history are doomed to repeat its mistakes. You might think that failing to learn from mistakes that you yourself have written about is especially careless.
