100 years later

Travel back in time to 1917 to talk to a starry-eyed Bolshevik in the immediate aftermath of the Russian Revolution. Tell him that you are sorry to have to tell him that the brave new world he imagines communism will usher in, is an illusion - a horrible illusion; that in the next six decades 100 million people will die as a result of the excesses and failures of communism, 20 million in the Soviet Union alone; that the next Soviet leader will ally with a German dictator who will exterminate over 10 million (6 million of whom are Jews); that there will be a massive world war in which millions more combatants and innocents will die; tell him this, and he will tell you you are mad, delirious and dangerous.
