BOAC,
That really isn't fair at all. There are all kinds of people in the military, some are more likely to introspect and reflect on the killing and misery caused to both sides in a war and some aren't. It's simply untrue and unfair to suggest because someone can have empathy with the enemy that they would not be effective at doing their job when it was required of them.
So, if that was what CM was saying then he was IMHO dead wrong.
