An interesting post, Kinergy. I have read the Rummel's book Death by Government.  Your question can also be asked in a slightly different way:  Who killed the largest number of their own people? and then answered in terms of the leaders of those countries.  Rummel gives this order: Stalin Mao  Hitler Lenin Chiang Kai Sheck I find it interesting that so much emphasis is always placed on what I might facetiously term The Bronze Medal winner, and how the others are so comparatively neglected. Just curious... are they counting jews and the german soldiers that died during WW2 as Hitler's own people?
