Agree Pericles. Much of it is back room idle diplomatic chatter made public - nothing that should concern anyone as regards national security.

I suspect a few of the observations as in Jinny's link might have more impact as regards general perceptions regarding terrorism and who wants to attack whom.

It may not be all that innocent.
One item refers to the Iranian champion cyclist, not by name but his
winning event who provided some info or something.
That could be fatal in a place like Iran.

Actually Pericles I would disagree with (that mentioned comment) about it not being serious;
There are a lot of considerable benefits in the diplomatic sphere from these leaks- not the least of these are countries wasting efforts and resources pursuing diplomatic dead-ends with countries that really have not much place in policy to work with them, and of course the domestic concern in many nations that their presidents or PMs are taking bribes from other countries to agree to some rather adverse policy (like the USA bribing the national leaders of Slovenia or of the Caribbean nations to take Guantanamo inmates).

And of course the finger-pointing at the wrong culprits for wrongdoings (The US drone attack and the anti-Iranian lobbying).

Hmm, my spidy censors are in overdrive over this one, something stinks.

Sarah Palin had these questions for the Obama administration:
Not that I'm a Palin supporter, sorry, Al :)
But she does raise some interesting questions.

"""
First and foremost, what steps were taken to stop Wikileaks director Julian Assange from distributing this highly sensitive classified material especially after he had already published material not once but twice in the previous months? Assange is not a “journalist,” any more than the “editor” of al Qaeda’s new English-language magazine Inspire is a “journalist.” He is an anti-American operative with blood on his hands. His past posting of classified documents revealed the identity of more than 100 Afghan sources to the Taliban. Why was he not pursued with the same urgency we pursue al Qaeda and Taliban leaders?

What if any diplomatic pressure was brought to bear on NATO, EU, and other allies to disrupt Wikileaks’ technical infrastructure? Did we use all the cyber tools at our disposal to permanently dismantle Wikileaks? Were individuals working for Wikileaks on these document leaks investigated? Shouldn’t they at least have had their financial assets frozen just as we do to individuals who provide material support for terrorist organizations?

Most importantly, serious questions must also be asked of the U.S. intelligence system. How was it possible that a 22-year-old Private First Class could get unrestricted access to so much highly sensitive information? And how was it possible that he could copy and distribute these files without anyone noticing that security was compromised?

To me, I smell a false flag operation to restrict our internet usage.
Any talk of implementing filters in any democratic country is met with huge cries from the plebs as witnessed when Conroy wanted one here (We were test subjects I reckon) Sure they have released a few juicy bits so they can scream national security, but mostly it's smoko room bulls't and just enough to bring in new rules governing the internet. Obama wants and internet kill switch but probably wants to filter the internet even more than our own Commy, Conroy.
This smells of a classic problem, reaction, solution ploy so well executed by governments all the time.

However, one must remember that only a small percentage of the 2 million or so files have so far been released, so it's anyone guess what they might contain.

His next release is about some big US bank. This is kinda interesting, but I'll wait to see what it contains before say anything else.

The problem with wikileaks publishing all the confidential cables is pretty much the same as publishing anyone's private mail. A lot of what is said in confidence can be very damaging especially out of context.

For example my cousin sent an email to her mum with some snippy comments to her sister. Her mum then replied to her and cc ed her sister forgetting that the old email was appended. The result is much bitterness and a distinct cold war between siblings, and both are now very careful about what they write to their mum.

The impact is very similar for the US diplomats with the real damage being that no one is likely to speak candidly to the US, and diplomats are likely to self censor their internal documents.

The result is all diplomatic activity grinds to a halt.

Considering much of diplomatic activity involves trade, this is a serious piece of economic sabotage.

If Wikileaks restricted himself to exposing abuse, he could claim journalistic integrity, however, this time he and his informers are likely to face the full wrath of the US and its allies. I seriously doubt that Iceland will have the stomach to shelter him after this.
