The most striking image in the tragic death of Italian security agent Nicola Calipari, killed by U.S. troops on the road to the airport with freed hostage/journalist Giuliana Sgrena, is simple and striking: national mourning. Americans avoid it. Our leaders avoid it. Our trained seal national media avoids it. Have you paused to watch a national prayer service for our dead in Iraq and Afghanistan over the past two bloody years? No, because it hasn't happened. Do you recall that national day of mourning for the 1,500 killed in the Iraq incursion? No, because President Bush has never named one. Yeah, we have local stories about "our heroes" killed in Fallujah, Baghdad, and Mosul - local funerals, local ceremonies of grief, local newspaper stories about the high school athlete or the volunteer fireman who went to war and never came home. Nothing national. Nothing American. All of Italy is mourning Calipari's death. His body is lying in state at the Tomb of the Unknown Soldier in Rome, where visitors have been paying their respects, and a state funeral was planned for Monday. President Carlo Azeglio Ciampi said he would award Calipari, a married father of two, the gold medal of valor for his heroism. In war zones, horrendous mistakes among jittery, scared, and heavily-armed troops will always lead to mistaken death and injury. It is part of the cost of war that our society has decided to accept, following the path laid out by our national leadership. What we don't have to accept is the national silence that greets the dead from an administration that doesn't want photographs taken of the coffins arriving Stateside. Why don't we mourn as a nation? The reason is simple and shocking and damning: because our leaders don't care.
