Laurence Beilenson had just stirred up the dovecotes with a book arguing that the United States should openly support and finance subversive movements within the Communist world. WFB begins by asking "whether he is in favor of doing anything to the Soviet Union in any way different from what the Soviet Union routinely does to us." LB: "No." WFB: "Have you no imagination?" LB: "I should like to be more successful. But the Soviet Union plays in our back yards; I merely propose that we play in theirs." Mr. Barth won't go so far as to characterize this idea as "offensive," but he does believe that "it would present, to be blunt about it, sir, a graver danger of subverting the character of the United States than of subverting the character of the Soviet Union or China, or any other country to which it were directed." And we're off on a heady discussion with historical illustrations stretching back to Hitler, Lenin, and Queen Elizabeth I.
