They still have all the bureaucracies and all that alleged "institutional knowledge", the consultants just came on top to provide scapegoats when some decisions turns out to be wrong. The bureaucracies are full of bureaucrats, and that's the problem. They don't want to make decisions (because they could be blamed), they've only ever learned how to maneuver in bureaucracies, so they're pretty much useless for anything but bureaucratic work. Turns out, even if you work in a bureaucracy, you still need to get some actual work done, e.g. on military policy. And they mostly can't. When they accidentally hire people that can, those people will smash their head against the wall of incompetence and political corruption until they leave, and who can blame them?
