More than that, congressional leaders often seem loath even to hear about events on the ground. During General Petraeus's visit to Washington last week, for example, House Democrats at first denied the Iraq commander an opportunity to brief them, citing "scheduling conflicts." And, when he finally did brief Congress, the evidence of progress that Petraeus was expected to present was dismissed before he even offered it. "He's the commander," Senator Carl Levin reasoned. "We always know that commanders are optimistic about their policies." The joke here, of course, is that Levin and his colleagues were not so long ago denouncing the Bush administration — and rightly so — for the sin of disparaging military expertise. True, civilians have no obligation to heed that expertise. They do, however, have an obligation to be informed or, at a minimum, to listen.
