The 6-month anniversary for Al Jazeera's English satellite TV channel comes up mid-month, and the many challenges that beset the organization appear to have bubbled to the surface in the months since the channel debuted November 16.

The many justifications for U.S. public diplomacy policy range from the concrete to the abstract. In forums such as this Web site, public diplomacy is described as both a specialized instrument for foreign policy promotion, as well as a symbol of the lofty ideals of promoting international dialogue and cultural understanding. Yet the instrumental aspect of public diplomacy typically boils down to the amplification of United States ethos.

From their offices in Washington and its suburbs, U.S. government officials charged with explaining the American way to publics abroad were put to the test last week by the Virginia Tech shootings.

When I give my course, "Propaganda and US Foreign Policy" (1) -- a historical overview of the subject -- I like to invite the class for a modest buffet dinner chez moi. The last time this get-together took place, it included a screening of Leni Riefenstahl's Triumph of the Will (1935), a film -- considered by some a propaganda classic -- that celebrates the 1934 Nazi Party Congress in Nuremberg. As the students ate their dessert, I turned on the DVD, and the Nazi director's troubling yet spectacular black-and-white images appeared.

U.S. public diplomacy programs aim to cultivate connections between foreign publics and the United States, which in theory fosters greater understanding of the United States, its motivations, and ultimate policy objectives. It should make sense of U.S. politics and reveal a more "objective" picture of the stewards of U.S. policy, who act at the behest of the American people. And it’s not an exact science. Strongly entrenched negative views about the U.S. in the Middle East (and elsewhere) continue to push the State Department towards new ideas for how this can be accomplished.

If there is one constant in discussion about public diplomacy in the United States these days, it is policy criticism. Such criticism has been a booming industry since the early days of the Bush administration – as U.S. popularity abroad continues to plummet. This is not to say, however, that the stewards of public diplomacy have ignored their charge. The now familiar Radio Sawa and Al-Hurra television supposedly beam models of pluralistic, democratic news culture to the Middle East.

The latest Middle East TV ratings that list actual tune-in of news channels, obtained exclusively by Worldcasting, show business as usual but also some surprises.

Al Jazeera, the Qatari government-owned channel, continues to hold forth in popularity in Egypt. Al Arabiya, funded in part by the Saudi government through a holding company, once again tops others in Saudi Arabia by a wide margin, but it also garnered impressive audience ratings in Iraq, where Alhurra, the U.S. government service, continues to trail its competition, there and elsewhere.

Since the events of September 11, 2001 the foreign policy establishment of Washington has exhausted much energy debating America's public diplomacy efforts. I've watched this debate with interest because I work on a contract basis for State Department public diplomacy programs. I have also tried to create private sector public diplomacy projects. I've traveled with foreign journalists, politicians, and other notable figures all over the United States. You might say that I'm a "foot soldier" in the public diplomacy battle.
