the official line ...

A new Pentagon policy directive for US military intelligence mandates information-sharing with US domestic agencies and foreign partners and recognizes the leading role of the new director of national intelligence.

Although both have been long-standing priorities for the Bush administration, the new directive, drafted in the office of Undersecretary of Defense for Intelligence James R. Clapper Jr. and published last month, is the first time that they have been promulgated in such a high-level policy document at the Pentagon.

We all get briefed on how important information sharing and collaboration is, but in practice it is actively discouraged. The older generations (everyone in charge) are afraid that someone will steal an idea or publish something before they do and get all the credit.

Yes.
