I am expressing in the book, in a sense, what many of us sense, even if many of us don't really want to confront the implications. The Congress, especially with regard to matters related to national security policy, has thrust power and authority to the executive branch. We have created an imperial presidency. The congress no longer is able to articulate a vision of what is the common good. The Congress exists primarily to ensure the reelection of members of Congress.
As the imperial presidency has accrued power, surrounding the imperial presidency has come to be this group of institutions called the National Security State. The CIA, the Joint Chiefs of Staff, the Office of the Secretary of Defense, the other intelligence agencies. Now, these have grown since the end of World War Two into this mammoth enterprise.
But the National Security State doesn't work. The National Security State was not able to identify the 9/11 conspiracy. Was not able to deflect the attackers on 9/11. The National Security State was not able to plan intelligently for the Iraq War. Even if you think that the Iraq War was necessary. They were not able to put together an intelligent workable plan for that war.
The National Security State has not been able to provide the resources necessary to fight this so called global war on terror. So, as the Congress has moved to the margins, as the President has moved to the center of our politics, the presidency itself has come to be, I think, less effective. The system is broken.
