In his most recent book, Thomas Friedman – New York Times columnist, Pulitzer Prize winner, presidential adviser – says of the Iraq War that he has ‘nothing but regret for the excessive price that America and Iraq have had to pay in lives and treasure’. The body count seems to be less cause for concern, however, than the fact that China, which has not been distracted from domestic infrastructure projects by pricey wars abroad, can now build a convention centre in approximately the same time it takes for the Washington Metro crew to repair two escalators in Friedman’s local subway station (the book is called That Used To Be Us: How America Fell Behind in the World It Invented and How We Can Come Back). Still, he’s come a long way since May 2003, when he said that the US military had to go ‘house to house from Basra to Baghdad’, wielding ‘a very big stick’ and instructing Iraqis to ‘Suck On This’.
