Friedman sparked criticism for writing that congressional ovations for Israeli Prime Minister Benjamin Netanyahu were "bought and paid for by the Israel lobby."  A letter from the American Jewish Committee objected that "Public opinion polls consistently show a high level of American ... support for and identification with Israel. This indicates that the people’s elected representatives are fully reflecting the will of the voters."  Friedman responded to criticism by writing: "In retrospect I probably should have used a more precise term like ‘engineered’ by the Israel lobby – a term that does not suggest grand conspiracy theories that I don’t subscribe to." 
“Excellent…[This book’s] insight is true and deeply important… The metaphor of a flat world, used by Friedman to describe the next phase of globalization, is ingenious…The book is done in Friedman’s trademark style. You travel with him, meet his wife and kids, learn about his friends and sit in on his interviews…[This method] works in making complicated ideas accessible…Friedman has a flair for business reporting and finds amusing stories about Wal-Mart, UPS, Dell, and JetBlue, among others, that relate to his basic theme.”
