I normally don't criticize the opinions of others in subjective matters such as this in a forum such as this, but Patrick, I find it somewhat disturbing that you would include Joseph Stalin and Mao Zedong on this list. Together they were responsible for the deaths of 50 million+ people and they ruled their countries with iron fists. Some people consider Stalin as more evil than Hitler. Have you included them on your list because you feel that they were sucessful as world leaders (an argument can be made for this because they did maintain the terrritorial integrity of their nations) or because you admire them and think that they were great men?
