I remember writing a column about Jeffrey Lucey, a 23-year-old Marine who was deeply depressed and suffering from post-traumatic stress disorder, or P.T.S.D., when he returned from Iraq after serving in the earliest months of the war. He described gruesome events that he had encountered and was harshly critical of himself. He drank to excess, had nightmares, withdrew from friends and wrecked the family car.  On the afternoon of June 22, 2004, he wrote a note that said, “It’s 4:35 p.m. and I am near completing my death.” He then hanged himself with a garden hose in the basement of his parents’ home.  Because we have chosen not to share the sacrifices of the wars in Iraq and Afghanistan, the terrible burden of these conflicts is being shouldered by an obscenely small portion of the population. Since this warrior class is so small, the same troops have to be sent into the war zones for tour after harrowing tour.  As the tours mount up, so do the mental health problems. Combat is crazy-making to start with. Multiple tours are recipes for complete meltdowns.  As the RAND Corporation reported in a study released last year:  “Not only is a higher proportion of the armed forces being deployed, but deployments have been longer, redeployment to combat has been common, and breaks between deployments have been infrequent.”  Recent attempts by the military to deal with some of the most egregious aspects of its deployment policies have amounted to much too little, much too late. The RAND study found that approximately 300,000 men and women who had served in Iraq and Afghanistan were already suffering from P.T.S.D. or major depression. That’s nearly one in every five returning veterans.  The mass-produced tragedies of war go far beyond combat deaths. Behind the abstract wall of RAND’s statistics is the immense real-life suffering of very real people. The toll includes the victims of violence and drunkenness and broken homes and suicides. Most of the stories never make their way into print. The public that professes such admiration and support for our fighting men and women are not interested.  Other studies have paralleled RAND’s in spotlighting the psychic toll of these wars. A CBS News survey found that veterans aged 20 to 24 were two to four times as likely to commit suicide as nonveterans the same age. A Time magazine cover story last year disclosed that “for the first time in history, a sizable and growing number of U.S. combat troops are taking daily doses of antidepressants to calm nerves strained by repeated and lengthy tours in Iraq and Afghanistan.”  We’re brutally and cold-bloodedly sacrificing the psychological well-being of these men and women, which should be a scandal. If these wars are so important to our national security, we should all be engaging in some form of serious sacrifice, and many more of us should be serving.  But the country soothes its conscience and tamps down its guilt with the cowardly invocation: “Oh, they’re volunteers. They knew what they were getting into.”  A version of this op-ed appears in print on , on Page A25 of the New York edition with the headline: War’s Psychic Toll. Today's Paper|Subscribe
The psychic toll of this foolish and apparently endless war in Iraq has been profound since Day 1. And the nation’s willful denial of that toll has been just as profound.
