A congressionally funded organization recommended Wednesday that the government overhaul its national security bureaucracy and congressional oversight of it, following closely on the heels of a similar commission.

The nonpartisan, nonprofit Project on National Security Reform argued that Congress should enact a new law detailing the precise responsibilities of each agency that is a part of the national security system.

Congress also should establish a new Select Committee on National Security in both the House and Senate that draws its members from the committees that oversee each national security agency, according to the organization, which is funded by both Congress and outside donors and was intended to re-evaluate the 1947 National Security Act.

The organization’s list of 34 “themes and recommendations” includes:

• Producing a quadrennial National Security Review much like the Quadrennial Defense Review.

• Preparing an integrated national security budget to present to Congress.

• Replacing the National Security Council and Homeland Security Council with a “President’s Security Council.”

• Establishing a single classification system for all national security agencies.

• Consolidating security clearance procedures for numerous agencies into one.

• Expanding the Foreign Service.

• Creating several interagency groups to better coordinate the national security bureaucracy.

“Unless we redesign what we have inherited from more than 60 years ago, even the wisest men and women upon whom we come to depend are doomed to see their most solid policy understandings crumble into the dust of failure,” the report said.

The congressionally created Commission on the Prevention of Weapons of Mass Destruction Proliferation and Terrorism was officially releasing its report the same day as the Project on National Security Reform, although its recommendations leaked out in advance and have already been widely reported in the media.
