Armies know all about killing. It is what they do, and ours does it more effectively than most. We are painfully coming to realize, however, that we are also especially good at killing our own ''from the inside out,'' silently, invisibly. In every major war since Korea, more of our veterans have taken their lives than have lost them in combat. The latest research, rooted in veteran testimony, reveals that the most severe and intractable PTSD - fraught with shame, despair, and suicide - stems from "moral injury".

The Washington Post's former Baghdad bureau chief, Rajiv Chandrasekaran, takes us into the Green Zone, headquarters for the American occupation in Iraq. In this bubble separated from wartime realities, the task of reconstructing Iraq is in the hands of 20-somethings chosen for their Republican Party loyalty. They pursue irrelevant neoconservative solutions and pie-in-the-sky policies instead of rebuilding looted buildings and restoring electricity, angering the locals and fueling the insurgency.

You've either done it or know someone who has: the one-night stand, the familiar outcome of a night spent at a bar, sometimes the sole payoff for your friend's irritating wedding, or the only relief from a disastrous vacation.
