What type of barriers was identified by the 9/11 Commission as impacting joint intelligence work?

The identification of structural barriers by the 9/11 Commission highlights the organizational challenges and inefficiencies that hinder effective joint intelligence work among various agencies. Structural barriers refer to the lack of coordination and communication between different government bodies, which can result from rigid hierarchies, differing missions, and bureaucratic obstacles.

The Commission urged for a more integrated approach to intelligence sharing, advocating for reforms to overcome these structural divides. They emphasized that the fragmentation within the intelligence community led to missed opportunities for collaboration, ultimately impacting national security and the ability to respond to terrorist threats effectively. The structural barriers were recognized as a fundamental issue that needed addressing for improved intelligence operation and coordination in the future.
