U.S. intelligence on Iraq was "dead wrong," dealing a blow to American credibility that will take years to undo, and spymasters still know disturbingly little about nuclear programs in countries like Iran and North Korea, a presidential commission reported on Thursday. The commission's bluntly written report, based on more than a year of investigations, offered a damning assessment of the intelligence that President George W. Bush used to launch the Iraq war two years ago and warned that flaws are "still all too common" throughout spy agencies. "We conclude that the intelligence community was dead wrong in almost all of its prewar judgments about Iraq's weapons of mass destruction," the commissioners wrote. At a time when the United States is accusing Iran of nuclear ambitions and pressuring North Korea on its nuclear programs, the report said: "Across the board, the intelligence community knows disturbingly little about the nuclear programs of many of the world's most dangerous actors." --More 2114 Local Time 1814 GMT
