He had a wide-ranging interest including politics and economics, and would vigorously debate any subject. Because of his Jewish heritage his views were strongly influenced from his experiences in Germany prior to WW11. Once asked about his experiences and how he felt about those days. His answer was that one should never underestimate the power of any demagogue to stir up nationalistic, xenophobic or racist attitudes. He said that whether it was the Germany under Hitler or Cambodia under Pol Pot there would always be danger for people if the wrong people were in charge. He really disliked nationalistic or jingoistic attitudes in politics whether it was local and overseas.
