We are seeing a level of partnership and collaboration in information sharing that we never have seen before. The national security community, now expanded to include homeland security, long has recognized the need for information sharing, and we have had some interfaces among these elements for some time.

Homeland security, the Global War on Terrorism and increased emphasis on nontraditional missions have placed a premium on information sharing. However, this remains a work in progress.
