Original Vietnam Pentagon Whistleblower Daniel Ellsberg, just shortly before the invasion of Iraq.  He skillfully compares his experiences on the inside during the Vietnam war to what was happening around the time of the presentation, and he offers his optimism for how he feels it can be changed.

It seems just as relevant today, as we witness a buildup to go into Iran under the same techniques.  An amazing speech, and a wonderful insider history lesson that anyone concerned with the mechanisms of war should absorb.
