President Bush, who has long brushed aside questions about his legacy, is opening up a bit during his final weeks in office.
At the White House on Monday, Bush called his HIV/AIDS program "one of the most important initiatives of my administration" and praised it as a resounding success.
And in a separate TV interview, the president was unusually blunt in identifying shortcomings during his tenure -- saying that his "biggest regret" was getting the intelligence wrong in Iraq and conceding that he was not ready to be a wartime president when he first took office.
"I think I was unprepared for war," Bush told ABC News. "In other words, I didn't campaign and say: 'Please vote for me. I'll be able to handle an attack.' In other words, I didn't anticipate war. Presidents -- one of the things about the modern presidency is that the unexpected will happen."
