What if communism was never introduced to the world?

Stalin would have used another pretext for his dictatorship.

Well aside from millions of people still being alive today in all possibility, I think the differnces between Marx;s theories and what was practiced in his name is pretty large.  I dont personally agree with either the theory or how it was practiced but there is a noticeable difference.  Techinically Marxism didnt account for the unwillingess of people to give up power and so was (according to Marxist theories I suppose) stuck the societies in a transistion phase.

Of course when we look at communism practiced especially in the USSR we see something so close to facism (its supposed opposite) its amazing they didnt get along better.  The irony being no one was more like nazi Germany than its arch foe, Stalinist Russia. 

So really, I dont think the world would be too different, Russia and others may have just adopted facism instead of communism, and they would have acted in much the same way.

I'm a student in search for numeral perspectives on the subject of alternate history concerning the existence of communism. What if communism was never introduced to the world?  My main focus is around  the 20th century during the period around the World Wars, but if relevant, I hope to trace it back to Karl Marx and his views, which brings up another question: did his perspective on communism and/or socialism provide a significant foundation to modern communism in the 20th century?  I'm solely looking for preferably a web or chain of events that would or would not occur if communism did not exist or, if relevant to Marx's views, expand beyond his ideas. Hope someone may generously contribute his/her time into giving me an insight and advice on the issue: What if communism was never introduced to the world? Thanks.
