It is the soldiers, their families, and the people of Iraq that pay the human costs. The tab so far: more than 3,000 dead U.S. troops, tens of thousands of wounded, over half a million Iraqi casualties, roughly 250,000 American servicemen and women struggling with PTSD, and almost 60,000 military marriages that have been broken by this war.

He'd been back for almost two months, but he was still checking to see where his weapon was every time he got in a vehicle. He drove aggressively, talked aggressively, and sometimes I could swear that he was breathing aggressively. This was not the man I married, this hard-eyed, hyper-vigilant stranger who spent his nights watching the dozens of DVDs that he got from soldiers he served with in Iraq. He couldn't sleep, and missed the adrenaline surge of constant, imminent danger. The amateur videos of combat eased the ache of withdrawal from war, but did nothing to heal my soldier's heart.

Emotional isolation is one of the hallmarks of post-combat mental health problems. The National Guard didn't conduct follow-up mental health screening or evaluations of the men in my husband's company until they had been home for almost eight months. Nearly a year later, in August of 2006, my husband was informed of his results: Post-Traumatic Stress Disorder (PTSD). It was obvious that he was suffering, but when I brought it up, he parroted what the military told him: "Give it time."
