Napoleon's+Distrust+-+By+seeming+to+be+friendly...

Stalin like Napoleon trusted nobody: even those who greatly supported him were removed from positions or often times murdered. Both Stalin and Napoleon trusted nobody, sided with nobody, and simply manipulated different groups of people to achieve their goals, whatever that might exactly be.

To learn more about Stalin's personality, I'll share a quote from our World History book, __Stalin and the Soviet Union__ (5):

'Stalin is too rude and this defect... [is] intolerable in a Secretary General. That is why I suggest that comrades think about a way of removing Stalin from his post and appointing another man in his stead who ... [is] more tolerant, more loyal, more polite and more considerate to his comrades, less capricious etc.'
