NPR's Robert Siegel talks with Tom Friedman, foreign affairs columnist for The New York Times, about Colin Powell's stance on the Iraq war. According to a new book by Washington Post journalist Bob Woodward, Powell was supportive of the war in public in an effort to win international support. But he was also concerned about the complications of a war. Woodward wrote that behind the scenes, Powell used language from one of Tom Friedman's columns in referring to the "Pottery Barn rule" of foreign policy. That is: "you break it, you own it."
