"Communism started as a form of socialism.However it was derailed by human greed for power and wealth".
Actually I disagree with the above statement!
The Bolshevik Revolution in Russia in the months and years after 1917 was viciously attacked and just about strangled by a right wing counter revolution with over a dozen foreign armies including British and American invading.They in turn supported right wing "white "armies led by the most reactionary anti semitic generals who were determined to conduct a bloodbath against the Russian working class led by the Bolshevik Party.

Russia had already seen some 20 million peole killed in the war between 1914 and 1917.The foreign invasions and the white russian onslaught meant millions more dead and the collapse of the economy and indeed the working class itself.The flower of revolutionary Russia died at the front defending the revolution and with the death of Lenin and the defeat of Trotsky Stalin was able to basically lead a counter revolution based on state capitalism and a form of Russian nationalism. The revolution had been choked to death.

Stalin through the control of the state apparatus murdered and imprisoned the bolsheviks and it is interesting to note that almost all the original leaders of the revolution were killed by him including his most implacable foe ,Trotsky.While Stalin stood for a vile kind of russian nationalism Trotsky was a revolutionary internationalist and a long time opponent of capitalism and its barbaric wars.Incidentally ,Trotsky was firmly opposed to any "party line" on culture and art.In this he differed completely from the Stalinists who followed a cultural line that celebrated the motherland and Stalin himself.
If the revolution was defeated by power and greed it was conducted on behalf of a imperial capitalism wading through the blood of the first world war to ensure that their rule was not challenged by revolutionary communism or the bolshevik revolution of 1917.
