To all those who have written reviews here before me: I'm criticizing this book and I'm neither a Republican nor a Democrat. I'm a native Iraqi. David Phillips is no doubt an insider and his book unveils a lot of the confusion within the administration on how to handle Iraq. This book is good as an assessment of the performance of the administration at large. I don't believe it is good to explain the American failure in Iraq.
From an Iraqi perspective, America's endeavor in Iraq came to a bitter end not because of State and DoD rivalry. America failed because both State and DoD didn't understand Iraq's language, culture, sociology and anthropology. Failure happened because experts like Phillips analyzed and assessed the situation there from the comfort of their offices inside the beltway in Washington DC.
Before writing on Losing Iraq, try first Understanding it. Phillips's book should be put in this context. Still, the book has good information on the need to get the administration's house in order if the United States is to regain its leading role in the world, yet Losing Iraq falls shorts on debating the Iraq issue from outside American partisanship.
