"I agree with your point that there are good people working in govt but I fail to see how the abundance of secrecy helps them do their jobs better."
Then I don't think you really understand statecraft or warfare. Two essential components of any sovereign nation. No offense meant. Just saying, secrecy are central tenants of both of those, and they are two of the most important functions of government.
I was arguing a bit at the extreme, in reaction to the other extreme. No doubt some secrecy will continue, but it would be preferable if there were a lot less than there is now.
You imply that the state/military would collapse without secrecy but haven't given any concrete reason why except perhaps, "that's how it's done." Tenets also implies belief. The world is changing and people will need to adjust regardless of what they believe in.
