The number is 3,422. That’s how many members of the U.S. military have paid the supreme sacrifice in the war in Iraq over the last four years. But on this Memorial Day, when the nation remembers our war dead, how many of them did we know? The reality for most of us is that, in fact, we don’t know any of these 3,422 who laid down their lives for country and family. Nor do we know their 25,549 comrades who have been wounded in this war. If we have family over there, all we know is the quiet prayer that God would keep our loved one from adding to either statistic.
