Its a case by case on whether it should be released. Some of the leaked stuff at least seems positive like the other Arab states don't like Iran being nuclear. Which eases the fear that if we do bomb the hell or just nuke Iran, there won't be this massive Middle East roar more like a slow clap. The Chinese espionage stuff does China no favors on the global stage. As for everything else, I am not sure what two year old memos are going to do to harm troops unless it specifies where troops and equipment will be. Then, they should be prosecuted to the fullest extent of the law regardless of where they live.
I am not sure where this stuff was during the Bush years, but since Obama has taken off its a twice a year event. Seems to me whoever his feeding this info is probably not a fan of the current administration. Speaking of Obama, he needs to stop condemning most of this stuff. He ran on a platform of a running this war in a more open fashion, its pretty hypocritical to denounce information that was covered up or continues to be covered up by the military. Obama also pretty much bought into these wars or be forced to continue these things either by the chiefs or polling or not wanting to give the GOP a weapon in re-election. Regardless, I think he has failed in regards to certain aspects of what he was elected to do to end these wars. And make no mistake, he was elected to end these wars not continue them.
One line mentioned in the CNN article says what I think about this:
"There should be no misconception that Mr. Assange passively operates a forum for others to exploit their misappropriation of classified information"
Much of this information itself might not be shocking, but when you start reading into it with an anti-american stance it can be condemning and convince people to act a certain way. Like, if Iran knows it will get no support, they might as well go on the offence instead of waiting to be attacked. Or that backing the USA -might- have if they decide to take action might now disappear because there is a difference between secretly supporting someone and saying it in public.
Funny/Interesting is that here in the Netherlands none of points in the CNN article made the news. Here it's all about comments about the various European leaders. Berlusconi was labelled as vain and incompetent, Putin and Medvedev are Batman and Robin, etc etc. While probably said by very minor officials this can't be good for alliances.
I figure you guys up there in Canada should be safe to keep on playing beerhunter (1000 points to anyone who knows the reference) and farming cattle, since the dead cow the American one ate was born in 97.
