your connection to The Boston Globe  Kay implores US to admit
mistakes in Iraq  CAMBRIDGE -- The former chief US weapons
inspector in Iraq warned yesterday that the United States is in
"grave danger" of destroying its credibility at home and abroad
if it does not own up to its mistakes in Iraq.  "The cost of our
mistakes . . . with regard to the explanation of why we went to
war in Iraq are far greater than Iraq itself," David Kay said in
a speech at Harvard University's John F. Kennedy School of
Government.  "We are in grave danger of having destroyed our
credibility internationally and domestically with regard to
warning about future events," he said. "The answer is to admit
you were wrong, and what I find most disturbing around
Washington . . . is the belief . . . you can never admit you're
wrong."  Kay's comments came as the White House sought to fend
off accusations from its former antiterrorism chief, Richard
Clarke, who said President Bush ignored the Al Qaeda threat
before the Sept. 11, 2001, attacks
