Once a year, the world’s leaders descend on New York for the UN’s blue ribbon event, the cumbersomely-titled UN General Assembly’s General Debate.

This year, the build-up has been dominated by the Palestinian Authority’s planned bid to become the 194th member of the UN, following South Sudan’s incorporation earlier in the year.

Notwithstanding any last minute deals, Palestinian Authority President Mahmoud Abbas will personally submit the application to Secretary-General Ban Ki-moon on Friday, September 23, after Abbas has delivered his speech to assembled leaders.

Indeed, Friday’s session is set to be a cracker, since it also features Israeli Prime Minister Benyamin Netanyahu’s speech, in which he must surely address the issue. And yet while the Palestinian membership-issue is grabbing all the headlines, there’s plenty of other highlights.

Ahead of the formal UNGA opening today, there was a high-level meeting on Libya yesterday, the first since the UN formally recognised the Transitional National Council as the official representative of Libya last Friday. 

US President Barack Obama met privately for the first time with TNC Chairman Mustafa Abdel Jalil, and held separate summits with President Hamid Karzai before he returned to Aghanistan to join the mourning of the assassinated leader Burhanuddin Rabbani.

Tuesday also saw French Foreign Minister Alain Juppe host a ministerial-level meeting of the so-called Deauville Partnership, a G20-offshoot dedicated to supporting fledgling Arab democracies.

The Debate kicks off today with an address by the Brazilian President, the first for Dilma Rousseff since she took office in January and no doubt a welcome relief from domestic troubles.

A notable absence, though, is Russian leader Dmitry Mevedev, who has chosen to delegate responsibilities this year to Foreign Minister Sergey Lavrov.

In the afternoon South Africa’s Jacob Zuma will be speaking. On Thursday morning, Mahmoud Ahmadinejad gives his traditionally polemical speech (who can forget last year, when he alluded to the 9/11 attacks being a conspiracy). British Prime Minister David Cameron also speaks that session.

Highlights from the afternoon session on Thursday include an inaugural address by newly-elected Peruvian President Ollanta Humala, an address from ageing despot Robert Mugabe, and also remarks from Turkish Prime Minister Recep Tayyip Erdogan, whose star is in the ascendancy amid Turkey’s role in the Arab Spring.

On the sidelines that day, UN Secretary General Ban Ki-moon is hosting a UN High-Level Meeting on Nuclear Safety and Security, likely to focus significantly on lessons to be learned from the crisis at Japan’s Fukushima Daiichi plant back in March. Friday, as we’ve seen, is all about the Palestinian-membership issue.

But in the morning there is also a first-time address from new Japanese Prime Minister Yoshihiko Noda , who is expected to put in appearance also at the nuclear safety meeting. That afternoon South Sudanese President Salva Kiir – who meets one on one with President Obama earlier in the week – will give his country’s address for the first time since it became member number 193 last July

Sadly, one of the traditionally more entertaining speakers – Venezuela’s Hugo Chavez – is not expected to make the journey to New York this time, as he is recovering from a fourth round of chemotherapy for cancer discovered earlier in the year.

The Admiral is the US Chief of Naval Operations and he gave these remarks to a Public Relations Strategic Communications Summit in June.

The general message is that the US Navy realised it could no longer afford not to participate in social media despite potential security risks and the challenges of a "dizzying" communications environment.

The speech marks a significant departure from the guidance in the US Navy’s social media handbook issued last year.

The 2010 manual discouraged Navy leaders from allowing too many individual units to set up social media accounts and urged commanders to establish a single "command presence". 

In this speech, Adm. Roughead instead argues that the Navy’s leaders need to understand that they command a "workforce of communicators".

He emphasised a transparent approach so that Navy leaders could listen to their subordinates and connect with the communities they were serving.

The Admiral cited the response to the earthquake and Tsunami in Japan as an example of how local commands could provide speedy updates on the crisis situation and reply to questions from the United States. 

He recognised, however, that the Navy has "only recently started to come to terms with the demand for radical transparency."   

The full speech is available here, but a few other sentences that I think are worth picking out:    

1. "For whether we embrace the fundamental communications changes underway today or not, our talented young workforce not only embraces them, they know nothing else. As leaders, then, it’s not enough that we keep pace with these changes – we must lead the change."

2. "I submit to you that in today’s media environment, as leaders – whether we recognize it or not – we are no longer simply leading a workforce of employees or, in my case, Sailors. We are leading a workforce of communicators."

3. "…it soon became clear to me that opting out [of engaging in social media] neither guaranteed security, nor served our interests in transparency, outreach, and advocacy. Rather than consider whether we could afford to participate, we came to the conclusion that we couldn’t afford not to participate."

4. "So we joined that conversation, and the term that I’ve used is, “we’re burning the boats.” There’s no going back. We’re committed irreversibly, and in the end it was one of the easiest decisions I’ve made as the Chief of Naval Operations."
