This question has thus far been considered off-limits, not to be raised in polite company, and certainly not in the mainstream media. It has been permissible, to be sure, to ask whether the war during the past several years has been justified by those attacks so many years ago. But one has not been allowed to ask whether the original invasion was justified by the 9/11 attacks.
However, what can be designated the "McChrystal Moment" - the probably brief period during which the media are again focused on the war in Afghanistan in the wake of the Rolling Stone story about General Stanley McChrystal, the commander of US and NATO forces in Afghanistan, which led to his resignation - provides the best opportunity for some time to raise fundamental questions about this war. Various commentators have already been asking some pretty basic questions: about the effectiveness and affordability of the present "counterinsurgency strategy" and even whether American fighting forces should remain in Afghanistan at all. But I am interested in an even more fundamental question: Whether this war was ever really justified by the publicly given reason: the terrorist attacks of September 11, 2001.
