Three days after 9/11, George W Bush began to notify American allies, and particularly England, of his intent to launch a military campaign against Iraq—a country unconnected to the terrorist attacks. What followed was more than a year of wrangling, as foreign leaders attempted without success to reign in Bush, until they finally faced the choice between siding with the president or making a historic break with the United States. This is the never-before-told full story of that struggle, as depicted in 500 Days, a new book by Kurt Eichenwald.
