This is the ultimate in naivete. In a competitive "survival of the fittest" world does it make sense to reveal all of your thoughts and knowledge?
Would you play in a poker game where you are revealing your cards and everybody else is hiding theirs?
I don't see China, Russia, or even the Vatican laying bare all of their information.
In a competitive world where you are a democracy and there are facts that your government leaders are stumblebums, does not your survival require knowing those facst so that the People who control the government can take corrective action.
We are not talking about publishing the security codes for the communications for our troops in Afghanastan. We are talking about information like the decision to resolve the palestinian question BEFORE we deal with the Iran nuke problem. like the former is going to happen in God's lifetime.
How about a Chess game where you have a Grand Master making all the moves on one side and you have the combined talents of 300,000,000 free citizens analyzing his moves and making suggestions as to the countermoves on the other side.
The strength of our Democracy is not our ability to execute things in secret but rather our ability to count on a free citizenry individual and collectively to stand up to the plate and do the right things on their own account with their own situational awareness. Free information is the strength of a democratic society, not its weakness.
Again, let me say, there is information that is genuinely classified because harm to the government will result. And then there is all the stuff that is marked classified because it is administratively convenient to do so, but which actually is not.
