As we move forward the needs for advancing Intelligence that is tactical rather than strategic is going to require a change in CIA/NSA/DOD efforts. In the past each of the intelligence services has sliced up and duplicated efforts and no amount of substantial political wrangling has changed that. I'm currently reading a few good books that look at information sharing and operational versus intelligence analysis.
