In a speech to a West Point military academy graduation on June 2 2001 that foreshadows 911, Wolfowitz reminds the students to think of two words, "surprise" and "courage". He then goes on to describe the intelligence breakdowns that allowed the Japanese to successfully attack Peal harbor. He talks about how "missed signals" and "warnings" and "expectations of the familiar" lead to such disasters and get governments and societies in to trouble. In a nutshell, he's psychologically prepping the students for 911.
"Rebuilding America's Defenses-Creating Tomorrow's Dominant Force...
...Further, the process of transformation, even if it brings revolutionary change, is likely to be a long one, absent some catastrophic and catalyzing event––like a new Pearl Harbor"

Notice at 3:27 in to the vid when talking about a book called "The Great Illusion" and how the author argues that war among nations is no longer profitable and therefore obsolete, Wolfowitz, president of the World Bank, waves his hand as if to dismiss this notion and begins to laugh. He then says that after the assassination of archduke Ferdinand, "the notion of the great illusion yielded to the reality of the great war."
