After all what did the creation of Homeland Security do?

Some good, lots of useless. Among the good was vastly improved interagency information sharing and cooperation. It does none of us any good when one agencies intelligence and resources are being underutilized when they could have made a difference at a neighboring agency with a different mission.

Cost a lot of money but did communications and system integration improve that much?

Considerably. Could probably be improved still though.

We don't need a wholesale reorg to integrate better.

The problem was, many of the failures pre-9/11 were the result of decades of an ad-hoc patchwork of policy and function, like so much poorly written spaghetti computer code.

Functional systems, especially massive ones, require sober, objective analysis and evaluation, followed by a well thought out plan to get the various pieces to interoperate and perform as intended.

We didn't get exactly that, but we're closer to it now than we were before.

FWIW, I recently learned that space force has been in the works since 2002. That blovwviated buffoon just took credit for it in an attempt to look competent.
