An Ancient Connection

The troubles and exploits of the returning war veteran represent a searing slice of reality. They have served as a recurring artistic theme throughout history — from Homer’s “Odyssey” to the World War I novel “All Quiet on the Western Front,” from the post-Vietnam-era movie “The Deer Hunter” to last fall’s film “In the Valley of Elah.”

At the heart of these tales lie warriors plagued by the kind of psychic wounds that have always afflicted some fraction of combat veterans. In an online course for health professionals, Capt. William P. Nash, the combat/operational stress control coordinator for the Marines, reaches back to Sophocles’ account of Ajax, who slipped into a depression after the Trojan War, slaughtered a flock of sheep in a crazed state and then fell on his own sword.

The nature of the counterinsurgency war in Iraq, where there is no traditional front line, has amplified the stresses of combat, and multiple tours of duty — a third of the troops involved in Iraq and Afghanistan have deployed more than once — ratchet up those stresses.

In earlier eras, various labels attached to the psychological injuries of war: soldier’s heart, shell shock, Vietnam disorder. Today the focus is on PTSD, but military health care officials are seeing a spectrum of psychological issues, with an estimated half of the returning National Guard members, 38 percent of soldiers and 31 percent of marines reporting mental health problems, according to a Pentagon task force.

Decades of studies on the problems of Vietnam veterans have established links between combat trauma and higher rates of unemployment, homelessness, gun ownership, child abuse, domestic violence, substance abuse — and criminality. On a less scientific level, such links have long been known.

“The connection between war and crime is unfortunately very ancient,” said Dr. Shay, the V.A. psychiatrist and author. “The first thing that Odysseus did after he left Troy was to launch a pirate raid on Ismarus. Ending up in trouble with the law has always been a final common pathway for some portion of psychologically injured veterans.”

The National Vietnam Veterans Readjustment Study, considered the most thorough analysis of this population, found that 15 percent of the male veterans still suffered from full-blown post-traumatic stress disorder more than a decade after the war ended. Half of the veterans with active PTSD had been arrested or in jail at least once, and 34.2 percent more than once. Some 11.5 percent of them had been convicted of felonies, and veterans are more likely to have committed violent crimes than nonveterans, according to government studies. In the mid-1980s, with so many Vietnam veterans behind bars that Vietnam Veterans of America created chapters in prisons, veterans made up a fifth of the nation’s inmate population.

As Iraq and Afghanistan veterans get enmeshed in the criminal justice system, former advocates for Vietnam veterans are disheartened by what they see as history repeating itself.

“These guys today, I recognize the hole in their souls,” said Hector Villarreal, a criminal defense lawyer in Mission, Tex., who briefly represented a three-time Iraq combat veteran charged with manslaughter.

Brockton D. Hunter, a criminal defense lawyer in Minneapolis, told colleagues in a recent lecture at the Minnesota State Bar Association that society should try harder to prevent veterans from self-destructing.

“To truly support our troops, we need to apply our lessons from history and newfound knowledge about PTSD to help the most troubled of our returning veterans,” Mr. Hunter said. “To deny the frequent connection between combat trauma and subsequent criminal behavior is to deny one of the direct societal costs of war and to discard another generation of troubled heroes.”
