Mr Rudd has had strained relations with Jakarta, particularly over the passage of asylum seekers heading by boat to Australia. As the website news.com.au noted: "Kevin Rudd can't do it – no matter how hard he tries – but Australian diplomat Adelle Neary, from Adelaide, has won over the hearts and minds of Indonesia."

Confucius institutes are part of a global campaign, funded by Beijing, to promote Chinese language and culture. However, the involvement of the Chinese one-party state, and its soft power ambitions, have generated some opposition. The siting of these centres in universities and public schools also makes them contentious.

The Australia Network has been our venture into this way of building national ''soft power'' - in other words, winning friends and understanding overseas through television news and entertainment. It had an uncertain start as an ABC offshoot with some additional funding from advertising.

Diplomacy needs to be backed by strength, but the US has plenty without militarizing Asia and the Pacific more than it already has. The peaceful resolution of these conflicts depends upon China having a role in the decision-making process, but this will require the US to step back and forego its desire for primacy in the region. And it will require the same of China.

Airpower diplomacy, also known as building partnerships by the U.S. Air Force, offers some distinct advantages over any alternatives. Best thought of as the non-kinetic application of air, space, and cyber power, airpower diplomacy is a form of soft power that’s useful in strengthening existing relationships and developing new ones—while protecting American interests.

Soft power and public diplomacy activities were rammed up ahead of the East Asian Summit (EAS) in Bali to lay the engagement groundwork. In Indonesia, a Department of Defence-funded integrated maritime surveillance system has just been handed over to the Indonesian government, with the US committed to supporting the programme until 2014.

So Obama has left his mark on the Australia-US alliance:...an historic speech on Asia strategy, an important shift towards US military access... But as a major public diplomacy opportunity to consolidate America's closest Asia Pacific alliance, it could have been done considerably better.

The speech and doctrine was far less grounded in a liberal illusion of Obama as a cosmopolitan-in-chief. His public diplomacy on this trip was meant less to reassure and more to make plain America’s intent to augment its hard military power in Australia’s backyard. His believe in the efficacy of hard power is one of the most underappreciated aspect of his presidency.
