Ep. 13 The philosophy of Donald Rumsfeld, the Unknown Unknown, WMDs, and the Iraq War

The mindcrime liberty show discusses Donald Rumsfeld and one of the official justifications for the Iraq War which is the prevalence of WMDs in Iraq.  When Rumsfeld is asked a question about the prevalence of WMDs in Iraq and the link to terrorist organizations he responds with what amounts to a philosophy lecture.  Is Rumsfeld's philosophy lecture true or is it just  dodge to a simple question. What would be the kind of evidence to make Errol Morris or Slavoj Zizek happy. Do we apply the same stringent demands of evidence to other areas? Finally was Iraq ( and Saddam Hussein) really a threat to the US even if it did have WMDs.
