"Stalin impressed me from the first and my opinion of his abilities has not wavered. His personality made itself felt without effort or exaggeration. He had natural good manners, perhaps a Georgian inheritance. Though I knew the man to be without mercy, I respected the quality of his mind and even felt a sympathy which I have never been able entirely to analyse. Perhaps this was because of Stalin's pragmatic approach. It was easy to forget that I was talking to a Party man, certainly no one could have been less doctrinaire. I cannot believe that Stalin ever had any affinity with Marx, he never spoke of him as if he did. During our several meetings in the war, sometimes with Churchill but as often alone, I always found the encounter stimulating, grey and stern though the agenda often had to be. I have never known a man handle himself better in conference. Well-informed at all points that were of concern to him, Stalin was prudent but not slow. Seldom raising his voice, a good listener, prone to doodling, he was the quietest dictator I have ever known, with the exception of Dr. Salazar. Yet the strength was there, unmistakably."
