I'm pretty sure that the book was sent to the relevant government people to be vetted, before it was published. The first time around, someone in the government must have missed the details.
The second time around, I'm sure they combed through it and pointed out the things that they would prefer the author left out. After that, the modified book probably got the green light.
I don't see why you would want to be an ass and just republish the book again without talking to the people.
Since when does the government need to approve books for publication? You want to "be an ass" because as the author, you want those details out, and as the publisher, you know those details are what will sell the book.
Depending on what kind of security clearance you have/had, you sign some long-term (ie: for life) NDAs and other paperwork that gives the government right of refusal to allow you to publish (in any fashion) any work. Including things like your resume.
It's not something normal, regular, average citizens deal with, but for those who are trusted with highly sensitive knowledge, it's par for course.
