Book excerpt: In February 2003, Patrick Cockburn secretly crossed the Tigris river from Syria into Iraq just before the US/British invasion, and has covered the war ever since. In The Occupation, he provides a vivid and disturbing picture of a country in turmoil, and the dangers and privations endured by its people. The Occupation explores the mosaic of communities in Iraq, the US and Britain's failure to understand the country they were invading and how this led to fatal mistakes. Cockburn, who has been visiting Iraq since 1978, describes the disintegration of the country under the occupation. Travelling throughout Iraq, from the Kurdish north, to Baghdad, Falluja and Basra, he records the response of the country's population - Shia and Sunni, Arab and Kurd - to the invasion, the growth of the resistance and its transformation into a full-scale uprising. He explains why deepening religious and ethnic divisions drove the country towards civil war. Above all, Cockburn traces how the occupation's failure led to the collapse of the country, and the high price paid by Iraqis. He charts the impact of savage sectarian killings, rampant corruption and economic chaos on everyday life: from the near destruction of Baghdad's al-Mutanabi book market to the failure to supply electricity, water and, ironically, fuel to Iraq's population. The Occupation is a compelling portrait of a ravaged country, and the appalling consequences of imperial arrogance.
