Very interesting article. For many years I have been asking myself this same question. After decades of reading, all I concluded, the bottom line, is that both dictators were two twisted evil individuals with different names and absolute scorn for human life...regardless if the motive was race, ideology, power or religion or any combination thereof. At their level of evil, a million more or less to the tally of each does not make any difference IMHO. I know this is a theme that rises a lot of controversy, who is worse - but frankly at the levels they reached, sponsoring wickedness, Hitler for 12 years, and Stalin for roughly 30, they end being equivalent. That equally applies to their egos - giant - and obstination for dominance and supremacy. What actually puzzles me more is the question of how could such two individuals share the same timeline in history to set forth the perfect storm... and write together the darkest pages of human contemporary history.
