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.

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.

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).

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.
