What Does the Geneva Convention Say About S&M?
by Steven Greenhunt
Ninety-nine point nine-nine-nine percent of American soldiers in Iraq and Afghanistan are noble and honorable souls doing wonderful work. How do I know that? Well, the media, members of Congress and virtually every talking head I’ve seen on TV tell me that.

Why do Americans assume that their fellow Americans would never do the evil things that people from other countries do? Why do American commentators of the Left and Right insist that what took place was clearly an aberration, when evidence continues to portray a more widespread pattern of torture and abuse?

Let’s face another uncomfortable truth: The people on the front lines, carrying out the orders and doing the dirty work, are not always the most honorable people in society. That’s true when we’re talking about police forces and federal agents in America and it’s true about armed forces occupying foreign lands.

Think about it. Who becomes a member of the armed forces, especially during a booming economy?
I know there are good and decent people in the military. But often the kind of people attracted to such a career are people who: a) Have few other skills or options available to them; b) Like to give or take orders; c) Like to blow things up and kill people; d) Are most comfortable in a highly regimented, bureaucratic environment where they don’t have to make nuanced moral distinctions.
