An interesting perspective in the New Republic:

""The debate over the legitimacy of the Iraq War was never about whether or not Saddam Hussein possessed weapons of mass destruction at some point in history. It is well known that Saddam Hussein used a variety of chemical weapons against Iran during the Iran-Iraq War of the 1980s—and the U.S., eager to see the destruction of the nascent Islamic Republic of Iran, aided him in creating the program. ""
