But how can you understand a war without any knowledge of the society where it happens? It's like trying to understand birth without knowing anything about pregnancy or conception. Or like trying to understand our current economic collapse without knowing what a derivative is.

You [can] become part of someone else's narrative. Every once in a while I would get people asking me questions like, "If your husband is a Muslim, then why haven't you converted to Islam?" Interestingly enough, almost every person who asked me that was a Sunni, and it was their not-so-subtle way of implying that my Shiite husband was a bad Muslim for letting his infidel wife run around unconverted.

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.

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!

We're taught that domestic life is not a "serious" political topic, like war and peace, but the fact is that we spend most of our lives doing everyday things: at the dinner table, in the kitchen, washing dishes, grocery-shopping, commuting. These things make up the fabric of our lives.

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.

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.
