The second criticism - which we admit - was that we only look at the costs, not the benefits. And you really ought to do the calculations to see if there are alternative ways that are more effective at getting your objectives. "One was Bush saying, 'We don't go to war on the calculations of green eye-shaded accountants or economists.' And our response was, 'No, you don't decide to fight a response to Pearl Harbour on the basis of that, but when there's a war of choice, you at least use it to make sure your timing is right, that you've done the preparation. So what did the Republicans say? "They had two reactions," Stiglitz says wearily. Even that, Stiglitz says now, was deliberately conservative: "We didn't want to sound outlandish." The paper they wrote together, and published in January 2006, revised the figure sharply upwards, to between $1 and $2 trillion. The figure was so low, they didn't believe it, and decided to investigate. Some time in 2005, Stiglitz and Linda Bilmes, who also served as an economic adviser under Clinton, noted that the official Congressional Budget Office estimate for the cost of the war so far was of the order of $500bn. The Three Trillion Dollar War reveals the extent to which its effects have been, and will be, felt by everyone, from Wall Street to the British high street, from Iraqi civilians to African small traders, for years to come. Whatever their reservations - and there will be a few - representatives will have to listen, because not many authors with the authority of Stiglitz, a Nobel prize-winner in economics, an academic tempered by four years on Bill Clinton's Council of Economic Advisers and another three as chief economist at the World Bank (during which time he developed an influential critique of globalisation), will have written a book that so urgently redefines the terms in which to view an ongoing conflict. For two days non-stop he has been talking - at the LSE, at Chatham House, to television crews - and then he is flying to Washington to testify before Congress on the subject of his new book. Fitful spring sunshine is warming the neo-gothic limestone of the Houses of Parliament, and the knots of tourists wandering round them, but in a basement cafe on Millbank it is dark, and quiet, and Joseph Stiglitz is looking as though he hasn't had quite enough sleep.
