This is not merely a showbiz phenomenon but a leading indicator of where our entire culture is right now. It’s not just torture we want to avoid. Most Americans don’t want to hear, see or feel anything about Iraq, whether they support the war or oppose it. They want to look away, period, and have been doing so for some time.

That’s why last week’s testimony by Gen. David Petraeus and Ambassador Ryan Crocker was a nonevent beyond Washington. The cable networks duly presented the first day of hearings, but only, it seemed, because the show could be hyped as an “American Idol”-like competition in foreign-policy one-upmanship for the three remaining presidential candidates, all senators. When the hearings migrated to the House the next day, they vanished into the same black media hole where nearly all Iraq news now goes. If the Olympic torch hadn’t provided an excuse to cut away, no doubt any handy weather disturbance would have served instead.

The simple explanation for why we shun the war is that it has gone so badly. But another answer was provided in the hearings by Senator George Voinovich of Ohio, one of the growing number of Republican lawmakers who no longer bothers to hide his exasperation. He put his finger on the collective sense of shame (not to be confused with collective guilt) that has attended America’s Iraq project. “The truth of the matter,” Mr. Voinovich said, is that “we haven’t sacrificed one darn bit in this war, not one. Never been asked to pay for a dime, except for the people that we lost.”

This is how the war planners wanted it, of course. No new taxes, no draft, no photos of coffins, no inconveniences that might compel voters to ask tough questions. This strategy would have worked if the war had been the promised cakewalk. But now it has backfired. A home front that has not been asked to invest directly in a war, that has subcontracted it to a relatively small group of volunteers, can hardly be expected to feel it has a stake in the outcome five stalemated years on.

The original stakes (saving the world from mushroom clouds and an alleged ally of Osama bin Laden) evaporated so far back they seem to belong to another war entirely. What are the stakes we are asked to believe in now? In the largely unwatched House hearings on Wednesday, Representative Robert Wexler, a Florida Democrat, tried to get at this by asking what some 4,000 “sons and daughters” of America had died for.

The best General Petraeus could muster was a bit of bloodless Beltway-speak  “national interests”  followed by another halfhearted attempt to overstate Iraq’s centrality to the war on Al Qaeda and a future war on Iran. He couldn’t even argue that we’re on a humanitarian mission on behalf of the Iraqi people. That would require him to acknowledge that roughly five million of those people, 60 percent of them children, are now refugees receiving scant help from either our government or Nuri al-Maliki’s. That’s nearly a fifth of the Iraqi population  the equivalent of 60 million Americans  and another source of our shame.
