When the Bush mob attacks critics like Ms. Sheehan, its highest priority is to change the subject. If we talk about Richard Clarke's character, then we stop talking about the administration's pre-9/11 inattentiveness to terrorism. If Thomas Wilson is trashed as an insubordinate plant of the "liberal media," we forget the Pentagon's abysmal failure to give our troops adequate armor (a failure that persists today, eight months after he spoke up). If we focus on Joseph Wilson's wife, we lose the big picture of how the administration twisted intelligence to gin up the threat of Saddam's nonexistent W.M.D.'s.
