This video is not just conspiracy theorist bullpoop (I'm very careful about checking these kinds of things), and indeed nearly all of the footage and quotes are sourced directly from publicly available DoD media. If you Google 'em, you'll turn up hits like this one: http://www.darpa.mil/DARPATech2005/presentations/ato/honeyoverview.pdf
What remains to be determined, of course, is whether this plan is not just another SDI, but all the evidence gathered hitherto plus experts' intuition (and my currently less than expert, but growing intuition) suggest that it is not. The only thing I'm really skeptical about is the part about long-range weather prediction and weather control. Everything else is probably doable within a time frame of either years or decades.
The video influenced my blood flow in ways that would be inappropriate to discuss in a family-friendly setting such as this one.
