I think I'm still just as conflicted about the war as I always was. On the one hand, I was a soldier carrying out his duty, following his allegiance to his country and to the mission at hand. But yet, there was always this unease plaguing me. "What are we doing here?" "Are we really fixing this country or are we doing more harm than good?" And the most pressing question: "How do we pull ourselves out of this quicksand?" I think I'm still there in that white space you mentioned, trying to get clarity for myself on what this war did to us as a nation.

Wars always evolve over time, don't they? Iraq/Afghanistan is different than Vietnam, and Vietnam was different than Korea, and Korea was different than World War One, and so on. Some things remain the same, of course - one side fighting another over ideology or a patch of ground - but there are some aspects of combat life which differ radically than their predecessors.

With a profession such as investing, people see the 'doing' as the buying and selling. It is difficult to come home from work, and answer your spouse's question, 'what did you do today?' with 'well, I read a lot, and I talked a little.' If you're not buying or selling, you may feel you aren't doing anything.

The careful choice of words, the scrubbing of language, the calculated images we presented to the external audiences - those were all major parts of my daily life over there. So, some of that is going to seep over into what I showed in the novel and - more importantly - how I showed it.

There is no more "front" and "rear" where Fobbit-types would go to hide out in safer locations. In Iraq and Afghanistan, you engaged in a theater of operations that's 360 degrees at all times.

Seeing any war through the distortion of comedy is healthy. There is just too much absurdity and irony at play in a combat zone not to pay attention to it. At least that's how it struck me; others may have had an entirely different war experience.

Where the differences came in was the patina of ideology which the news media laid over everything. There's certainly a bias, to some degree, in the way the media portrays the military. I'm not saying that's entirely wrong - the Fourth Estate is there to hold generals and colonels accountable for their actions and decisions - but having reporters on the scene, reporting in real time certainly complicates things for the military mission.
