There is no doubt in my mind that some day Americans will look back on this time with the same sort of shame that we now look back on the McCarthy era. (In fact, the war on terror seems to me to be a bad remake of McCarthyism, with "terrorism" substituted for "communist", Iraq and Iran for Viet Nam and Russia, and (thank God) Keith Olberman playing Edward R. Murrow.)
On that theory, we should be having a Joseph Welch moment one of these days. Maybe this is it.
