This is an example of how Victoria Clark introduces a sub-chapter (President Salih's present problems). And indeed throughout her exploration of Yemen's history and character she really allows the reader to comprehend the hardy tribalism, the extreme violence fed by so much easy weaponry, the jihadist roots, the buffeting by outside forces, the corruption and poverty, the surprisingly dogged optimism, the Islamic variations, the scandalous qat cultivation ... it is all there. She explains why Aden is "the Cinderella of the East", how the various rebellions reoccur, why separation is still on some tribe's agenda, how Marxism took root here only to fail, and importantly why there is such an economic gulf separating Saudi Arabia and Yemen. The format is colourful and easy to read. The State and The Tribes: "the manner in which the competing authorities are constantly being challenged, tested and renegotiated" gives the book its superb title. I would have liked more informative maps and more photos, but the geography is explained well. I took this book on a recent holiday to Morocco and I was know as "Mr Yemen" because I always had this book with me (and open!).
