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 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.

With a profession such as investing, people see the 'doing' as the buying and selling.
