TEMPE, Ariz. (AP) -- Jeb Bush says it was a mistake to invade Iraq.
The Republican White House prospect clarified his position on the war his brother authorized. The former Florida governor ended several days of confusion about his foreign policy while campaigning Thursday in Arizona.
Bush said that given the benefit of hindsight, "I would have not gone into Iraq."
In interviews earlier in the week, Bush refused to say whether he would have launched the 2003 invasion if he'd been in President George W. Bush's shoes. He said Thursday he was reluctant to say the invasion was the wrong decision because he didn't want to dishonor the lives of American troops killed there.
The justification for the war was based on faulty intelligence that Iraq possessed weapons of mass destruction.
