On a global level, history teaches us how kindness, more than hostility, can strengthen nations. Over the last few years, for example, the Guantanamo Bay Detention Camp has been a lightning rod for debate. Controversy reigns about the methods used to interrogate foreign detainees suspected of Taliban or Al-Qaeda involvements. After several years of harsher methods of interrogation, however, officials are finding that most of the productivity we see over time, in terms of collecting intelligence, comes from the milk of human kindness. When interrogators take time to earn the respect of a prisoner and approach the subject in a friendly and businesslike manner, they are most likely to give needed information. We can never underestimate the influence of human kindness.
