In a new book, "National Security and Double Government," Michael Glennon catalogs the ways that the defense and national security apparatus is effectively self-governing, with virtually no accountability, transparency, or checks and balances of any kind. He uses the term "double government": There's the one we elect, and then there's the one behind it, steering huge swaths of policy almost unchecked. Elected officials end up serving as mere cover for the real decisions made by the bureaucracy.
National security policy actually bubbles up from within the bureaucracy.
The ultimate problem is the pervasive political ignorance on the part of the American people.
The people have to take the bull by the horns. And that's a very difficult thing to do, because the ignorance is in many ways rational. There is very little profit to be had in learning about, and being active about, problems that you can't affect, policies that you can't change.
