...the ceremony was an entertaining celebration of British culture.  London had a tough act to follow after Beijing’s stunning ceremony in 2008. Yet, not only did London surpass expectations, but its display of self-confidence and soft power made a more powerful statement than Beijing’s mighty effort.

"I think my country Sudan has really hit rock bottom." Those were the last public words uttered by Usamah Mohamad, a 32-year-old Sudanese web developer-turned-citizen journalist, in a video announcing he would join protests against President Omar al-Bashir. Mohamad, popular under his Twitter handle "simsimt," was arrested the same day his video was aired. For the next month, his family had no idea where he was. Finally they learned he was in Khartoum's high security prison and were allowed to visit him last week.

President Obama's decision last year to call for the fall of the Assad regime, in which he was followed by Britain and other allies, was, it can be argued, a mistake. The reasons were understandable. First, the regime was behaving appallingly. Second, the US did not want to be behind the curve in another phase of the Arab spring, particularly as the Damascus government was, unlike the Mubarak government in Egypt, one which it had always disliked and which was tied to regional foes of America in the shape of Iran and Hezbollah in Lebanon.

The Chinese people I met while I was studying in the U.S. in the early 2000s gave me the strong impression of being aggressive in pursuing their goals. In many cases, five people shared a one-room studio to save on rent, though things might have changed now that China is the world’s second-largest economy in gross domestic product and trade. Back then, those who talked loudly at restaurants and attempted to buy a 10-dollar chair at half price at garage sales were mostly Chinese.

China’s ability to get what it wants through attraction and persuasion rests on a number of factors: its culture (witness the Confucius Institutes it promotes); its values (particularly a successful growth model); and its foreign policies (for example, the pledge not to intervene in the internal affairs of other countries).

Chiefly through its state-controlled media, the Chinese government launched a campaign to highlight its peaceful rise and attractive culture by providing information about its ideas and value system. China’s charm offensive, however, is unlikely to bear much fruit if its public diplomacy strategy lacks a critical element: “a responsible China.”

On July 25, Department Secretary of State Bill Burns announced the creation of Networks of Diasporas in Engineering and Science, or NODES, at an event organized by the Office of the Science and Technology Advisor to the Secretary of State (STAS). At the same event, Under Secretary of State of Public Diplomacy and Public Affairs Tara Sonenshine launched the Science, Technology, and Innovation Expert Partnership.

Strengthening America’s brand. In Europe and most of the rest of the world (Muslim countries being important exceptions), the United States is significantly more favorably regarded than when he took office. That is bankable soft power.
