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.

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. I wanted to show readers that the larger politics of war and economics and U.S. foreign policy are inextricably bound to the supposedly trivial details of our everyday lives.

The Middle East is the only region in the world outside of sub-Saharan Africa where rates of malnutrition actually rose over the past decade or two, instead of falling.

Rulers like Egypt's Gamal Abdel Nasser started subsidizing bread as a way to buy loyalty, or at least obedience, and this system became so pervasive that the Tunisian scholar Larbi Sadiki described countries who used it as dimuqratiyyat al-khubz - "democracies of bread." But the problem with this system of offering bread in exchange for genuine democracy is that it can never last - sooner or later, the bread will run out, and people will start demanding bread and roses too.

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.

There hasn't been a lot written about it in the Western media. But in the Arab world, and Western Asia as a whole, Baghdad was always known as a famously bookish, intellectual city. There's an old saying that Cairo writes, Beirut publishes, and Baghdad reads.

There were a hundred booksellers in the old round city founded by the eighth-century caliph al-Mansur. The café and wine-drinking culture of Baghdad has been famous for centuries; there was a whole school of Iraqi poets who wrote poems about the wine bars of medieval Baghdad - the khamriyaat, or wine songs, that I quote in the book.
