It's disingenous for me to say that I wasn't trying to write a moral novel. By its very nature as a novel about the Iraq War, Fobbit steps into the political conversation. There's no way to avoid that. I can appreciate that readers are probably going to line up on one side of the novel or the other. I hope they go to those polar extremes, actually.

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.

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.

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.

The modern wars are also omnipresent in our electronic media - to be cynical about it, we now have 24 hours of non-stop bloodshed available to us. The internet and real-time media reporting were integrated into daily life in Iraq.

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.

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.
