Yeah, I agree it is a ludicrous proposition.
But these sorts of hypocrisies will manifest themselves when professed beliefs are tested.
 
The US Govt., and the 'page boys', are merely acting as expected.
Every Pres. in the past 30 or so years professed a belief in more open and transparent goverment while presiding over an exponential growth in classified materials.
We live in a world where everything to do with government is now routinely classified and secret, and its all to do service to the idea of 'national security'.
 
The mundane, everyday ordinariness of these 'secret' cables proves the point - too many things are secret that should be freely available and common knowledge.
It is not imperative to 'national security' to hide the fact that British Royals can be absolute dorks, or that the Sauds harbour an enmity towards Iran, or that Russia is largely a Mafia State etc, etc.
 
The proposition that Assange is not a journalist is just more of the smoke and mirrors leg-pulling of the past. You and I see it as a joke, but the game being played is for keeps.
The current arrangement suits oppressive paternalism and so many people long for a Big Daddy to take care of them. They sit in the big back seat and play their gameboys, only occassionally poking their heads up to say 'Are we there yet?' It is generally not noticed that the drive is only around and around the same block.
