7 July Wall Street Journal commentary - U.S. Soldiers Aren't Guilty Before a Verdict by Daniel Henninger.

... Military specialists will output case studies for years on how Iraq has altered the way war is waged by Americans -- on the battlefield and on the home front. Most interesting to know would be whether the war as perceived at home and the war as fought daily by our soldiers in Iraq became two separate realms of consciousness, the former barely related to the reality of the latter.

One benchmark in this process will be deciding which elements of the nation's military past are deemed relevant to taking the measure of this war. Outside the military colleges, the experience of World War II appears to have become largely irrelevant. The controlling benchmark today is whether any American military commitment can evade the vague moral abyss of the Vietnam War. Thus when the Haditha story broke open over Memorial Day it was analogized as "another My Lai," the storied 1968 killing, and cover-up, of hundreds of civilians in a Vietnamese village.

The reason for viewing Haditha through the moral sextant of My Lai is that My Lai significantly altered the political status of Vietnam in the U.S. It became a totem for U.S. behavior in Vietnam. So it is only natural that the My Lai template, however ill-fitting, would be pressed against Haditha to see if this one lurid story would break the back of the entire Iraq enterprise. And so the chairman of the Joint Chiefs shows up on TV the Fourth of July -- going on PR offense like any corporate product manager to ensure this isn't the one event that burns down the whole company. Fair or not, these are the new rules of political engagement in wartime America, and the government learns to play by them or risk being rolled off the field.

But what about the soldiers themselves? Nearly anyone who gets sucked into the media vortex -- celebrity, CEO, sports hero -- becomes mere cannon fodder, so assume the same for GIs involved in abuse or murder allegations. The Marines implicated in the Haditha incident are largely anonymous now, but each is being auditioned to play this war's Lt. William Calley. But first they have to be convicted of something.

The innocence or guilt of the individual soldiers implicated in Haditha or the other alleged abuse incidents is a lower-order concern to those fighting a PR war for the hearts and minds of the American people on Iraq. In the first effusion of media coverage of these events, the impression is weighted toward assuming guilt, and so when the pollsters call to ask about support for the war, the numbers fall. Mission accomplished -- unless a Gen. Pace can jump quickly enough on the other side of the public-impression teeter-totter...
