Mr. Brzezinski seems worried, as well he might. This is a man who knows his Washington:
A plausible scenario for a military collision with Iran involves Iraqi failure to meet the benchmarks; followed by accusations of Iranian responsibility for the failure; then by some provocation in Iraq or a terrorist act in the U.S. blamed on Iran; culminating in a "defensive" U.S. military action against Iran that plunges a lonely America into a spreading and deepening quagmire eventually ranging across Iraq, Iran, Afghanistan, and Pakistan.
A mythical historical narrative to justify the case for such a protracted and potentially expanding war is already being articulated. Initially justified by false claims about WMD's in Iraq, the war is now being redefined as the "decisive ideological struggle" of our time, reminiscent of the earlier collisions with Nazism and Stalinism. In that context, Islamist extremism and al Qaeda are presented as the equivalents of the threat posed by Nazi Germany and then Soviet Russia, and 9/11 as the equivalent of the Pearl Harbor attack which precipitated America's involvement in World War II.
