The Great October Revolution completed 99 years on October 25, 2016 and entered its centenary. It would not be an exaggeration to argue that this epochal event defined the Twentieth century in more than one ways. One is even tempted to contend that in some ways it defines our times as well. Despite the fact, that bourgeois hacks have read the obituaries of Socialism countless times, the October Revolution continues to inspire the struggling workers and stir the hearts of revolutionaries around the world. Despite the fact that the Socialist experiment in Soviet Union fell in 1956 and the sham "red flag" fell in the Soviet Union in 1990, the bourgeois propaganda machine has never stopped its diatribe against the Soviet Union and the greatness of the marvellous achievements that it succeeded to accomplish in a short life span of around 40 years. The specter of Communism still haunts them. The critical evaluation of the Soviet Socialist experiment is still not a settled question among serious Marxists-Leninists. How do we analyze the successes and failures of the Soviet Socialism? What do we need to learn from the Soviet experiment and what must we not? How do we understand the continuing significance of the October Revolution? And most importantly, what will be 'new' in the new socialist revolutions of the Twenty-first century? These are the questions that Marxist-Leninists must answer. Like any science, Marxism develops through 'redemptive activity'. The critical analysis of the Soviet Socialism is imperative for performing this 'redemptive activity'.
