The U.S. State Department has been working for several years to play a more active role in online communications.

Last week I attended "Face-off to Facebook: From the Nixon-Khruschev Debate to Public Diplomacy in the 21st Century", a conference sponsored by George Washington University's Institute for Public Diplomacy and Global Communication at the School of Media and Public Affairs. The event was a celebration of the 50th anniversary of the American National Exhibition in Moscow and the infamous impromptu tête-à-tête that took place between Vice President Richard Nixon and General Secretary Nikita Khruschev.

Edward R. Murrow's famous remark about the importance of "the last three feet" to bridge personal contact was not unexpectedly raised at last week's conference that I attended at George Washington University, on the 50th anniversary of the Nixon-Krushchev "Kitchen Debate" at the 1959 U.S. Exhibition in Moscow. But few may know that Murrow raised the last few feet issue informally, and more than once, with colleagues at CBS News in New York long before he uttered them as director of the U.S. Information Agency.
