Can declassified Gov't documents like ones at the National Archives be classified agian?

Answer 1

Yes.

In fact this happened several years ago after Clinton signed a policy letter requiring automatic declassification after 20 years. (Another one of those 'What were they thinking?' incidents that Clinton was infamous for among people concerned with national security.)

This cause more than a mild panic when CNWDI (Critical Nuclear Weapons Design Information) was declassified and published in the National Archives. When President Bush came into office he decided that we really do not want Iran, North Korea and Al Quadea to know how to make small, high-efficiency nuclear warheads - and ordered the information classified.

Answer 2

No once a document or piece of equipment has been declassifed it can not be classified again. Once it is seen by people with out a clearance it has to be declassified.
Example a top secret weapons system accidently get seen by a newsie and he prints the specis and prints. That weapons system has to be declassified because of being seen by unauthoritized persons.
Example: A Technician who works on a top secret missle system gets drunk and hits his or her commanding and gets court maritalled and six months in the bring. He or she loses any security clearances for that period of time. Ok! say they got out in two months for good behavior. But still for that six months they will not have a security clearance. They reoport back to their unit. Not thinking they are sent back to work on the top secret missile system with out a clearance. That missile system's security is compermised because a person who does not have clearance has had access it it and it is not longer considered secured therefore declassified.

I know the military seems to be taking it to the extreme but as a hangover from the cold war when it was a constant spy versus spy versus spy. But considering who are cropping up as Islamic terrorist these days not so extreme.

Although some super top secret items have been meant to be seen by the enemy. Take for example the Marine Corps F-4 Phantoms three stages of after burners as opposed to the Air force and Navy F-4 Phantoms with supposedly only two.
Marine Corps F-4 Phantoms top secret: able to into orbit and deliver nuclear weapons from orbit in space. Well in theory supposedly (on paper). And you can bet the Krelim spent tons of money and wasted valuable resources trying to design a defense system against it. And it was something that would supposedly work (on paper). But not in real life. Still the Russians had no choice but to try to build a defense against it.

Answer 3

I'm sure if the White House made a good argument for it in the name of national security, they could--or if they just had a Republican-Controlled congress that rubber stamped everything. However, the pursuit of it wouldn't make any sense since they're already been brought out of the closet.
