There's a long history in the Middle East of "bread intifadas," starting with 1977 in Egypt, when Anwar Sadat tried to lift bread subsidies. People rebelled and poured into Tahrir Square, shouting slogans against the government just like they did earlier this year. Sadat learned his lesson and kept bread subsidies in place, and so did a host of other Middle Eastern dictators - many of whom were propped up for years by the West, partly through subsidized American wheat.

As a journalist, or an anthropologist, the convention is that people are there for you to study, and they are your objects.

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.

Which is one of the dangers of immersion journalism: you can find yourself getting sucked into battles you have nothing to do with, in this case an ongoing battle between Muslims.

Americans are curious about the texture of everyday life in the Middle East because they rarely get to see it. I wanted readers to feel like they were sitting around the dinner table with me and my friends, hearing what average people really say and really think, [where] the dinner table is the best place to find out.

Being an American journalist can put people on the defensive. In countries where people assume the press is partisan, like in Lebanon, or where it had essentially become an extension of the government, like in Iraq, people tend to see a journalist as an agent of his or her government. That can be dangerous if the United States military is occupying their country, or aligned with their enemies.
