How can a country be home to sectarian militias and yet also to people who are educated, sophisticated, and pluralistic? This is not a simple matter. It's the kind of dialectical inquiry that's impossible to present in the world of Twitter feeds and newspapers where stories are shorter and shorter and more simplistic.

So much of what we see and hear about the Middle East focuses on what we call politics, which is essentially ideology. But when it comes to the Middle East, and especially the Arab world, simply depicting people as human beings is the most political thing you can do. And that's why I chose to write about food: food is inherently political, but it's also an essential part of people's real lives. It's where the public and private spheres connect.

Pedro Teixeira, the great Portuguese merchant-adventurer, wrote a beautiful description of a coffeehouse with windows overlooking the Tigris and the ruins of old Baghdad. That was in 1604, and he's visiting the same street that I write about in the book, named after Abu Nuwas, though it wasn't called that back then.

If you look at the list of the top wheat importers for 2010, almost half of them are Middle Eastern regimes: Egypt, Algeria, Iraq, Morocco, Yemen, Saudi Arabia, Libya, and Tunisia. Egypt is the number-one importer of wheat in the entire world. Tunisia leads the entire world in per capita wheat consumption. So it's no wonder that the revolutions began with Tunisians waving baguettes in the streets and Egyptians wearing helmets made of bread.

The irony is that Iraq actually has one of the richest and most sophisticated cuisines in the world. So many classic American or European foods - ceviche, albondigas, even the mint julep - have roots in Iraqi cuisine, which was a crossroads of Persian and Arab and Turkic traditions. The oldest written recipes in the world are from Iraq!

For my generation - the "Children of Nixon," as I call us in the book - the Lebanese civil war was an iconic event. Downtown Beirut became a metaphor for so many things: man's inhumanity to man, what Charles Bukowski called "the impossibility of being human." It shaped our perceptions of war and human nature, just as Vietnam did for our parents. We used it to understand how the world works.
