I found in traveling around the world that a great many people . . ., apparently well educated and sophisticated, were convinced that the people of the United States were in the grip of terror and that free speech and free press no longer existed here. They believed that the United States was fomenting a third world war and would presently start it, with Armageddon consequences for everyone else, and that the government of the United States smashed without mercy anyone who dared to oppose even by oral protests this headlong rush toward disaster.
These people could "prove" their opinions by quoting any number of Americans and American newspapers and magazines. That they were able to quote such American sources proved just the opposite, namely that we do continue to enjoy free speech even to express arrant nonsense and unpopular opinion, escaped them completely. (Robert Heinlein, 1953)
