During the Cold War, a group of Russian journalists toured the United States. On the final day of their visit, they were asked by their hosts for their impressions. 'I have to tell you,' said their spokesman, 'that we were astonished to find after reading all the newspapers and watching TV, that all the opinions on all the vital issues were by and large, the same. To get that result in our country, we imprison people, we tear out their fingernails. Here, you don’t have that. What’s the secret? How do you do it?'
