If Fobbit leaves a reader feeling stranded in some bland in-between territory, then I haven't done my job. But having said all that, I didn't consciously write the book with a particular moral intent. I took what I experienced and processed it through the sausage factory of fiction. It's up to readers to interpret what's on the page - as is the case with any novel.

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.

I think it's possible - perhaps even necessary - to find comedy in any war. I mean, look at the brilliant work which was done by Joseph Heller and Richard Hooker (M*A*S*H) and Jaroslav Hasek (The Good Soldier Svejk - which I haven't read, but have heard was funny).

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.

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.

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.
