TWO JOURNALISTS now on the staff of the Washington Post made extraordinary contributions to the research for this book. Robin Shulman conducted interviews and dug up documents in Egypt, Lebanon, Israel, Spain, France, and the United States. Her persistence, empathy, and eye for detail have made the book immeasurably stronger. After I drafted the manuscript, Julie Tate recontacted my interview subjects to deepen the research and recheck facts and interpretations. Her attention to detail and nuance, her passion for the subject matter, and her astonishing work ethic made an enormous difference.
