You should be watching C-Span right now. They are currently airing a forum recorded Friday at the University of Virginia’s Miller Center of Public Affairs on the future of CIA intelligence operations. The current speaker is former CIA spook Howard Hart.;
His near future outlook is quite bleak. The main reasons he cites for this are the time required to get a clandestine service officer trained, and problems with recruitment.
Oh, it was just cut short because of technical difficulties. I hope they air this again.
