They are, but I don't think the story is trying to say much about them that wouldn't be agreed with by the vast majority of its audience, and I think try to read in specifics is too much.

: We get a little of what ONI is thinking of with Sully's attitude. He acts
: distant and confident all at the same time like nothing can possibly touch
: him. Sully is like this right up until Ben is in front of the Senate Armed
: Forces Committee.

: The UNSC, including ONI, more or less is still acting as if they're in
: control of Earth and her colonies and not the civilian government. It's
: important to realize that there was once two unique military bodies
: separating Earth and the colonies, with the United Nations and the
: Colonial Administration Authority, respectively. The United Nations still
: exists as the governing body of Earth's nations and the UNSC has since
: absorbed the functions of the CAA and its military. When I say Earth I
: mean it in every little way.

My issue is that Earth, the solar system, the inner colonies, they're not to blame, because when I think of those I think of locations and people, and most of the people are civilians. Organizations, like ONI, are to blame. Pitting broader groups against each other is not going to help anyone (or, anyone but a select few people).
