Here's a thought on the cost to humanity from Bob Herbert's recent op-ed in the NYT:
"One of the reasons we’re in this state of nonstop warfare is the fact that so few Americans have had any personal stake in the wars in Iraq and Afghanistan. There is no draft and no direct financial hardship resulting from the wars. So we keep shipping other people’s children off to combat as if they were some sort of commodity, like coal or wheat, with no real regard for the terrible price so many have to pay, physically and psychologically.
Not only is this tragic, it is profoundly disrespectful. These are real men and women, courageous and mostly uncomplaining human beings, that we are sending into the war zones, and we owe them our most careful attention. Above all, we owe them an end to two wars that have gone on much too long."
