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.

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.

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.

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.

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.

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.
