You must not remember that when Trump tried to release
the embargoed material after the fifty year delay
imposed upon the release of the material by Congress
there was hue and cry from the "establishment" about
releasing it to the public. Reasons of "national security"
were given. There was large discussion about that
on this site.
The material is still hidden from the public as of this day.
Who is the US gov. protecting?
