BHO is not even a pale shadow of Joseph Vissarionovich Dzhugashvili, which is fortunate for us. To get a better picture of just what a combination of remarkable iron willed person combined with being a malevolent psychopath this man was read Simon Sebag Montefiore’s two books on Stalin,
Stalin: The Court of the Red Tsar and an even more remarkable work presenting a mass of newly available archival material, Young Stalin. Stalin was akin to some sort of Genghis Khan like figure transported to the 20th century.
