More than seven years after the invasion of Iraq, NBC's Brian Williams has decided that it was an "elective war."

Williams told NBC's Joe Scarborough Monday that he came to the conclusion during over the weekend during events observing the 10th year after the 9/11 attacks.

"Having listened to a lot of discussions on the war in Iraq at a lot of gatherings, I've settled on the word elective," Williams explained. "It was an elective war on the part of [President] George W. Bush because none of those pilots [who carried out the 9/11 attacks] were Iraqi, because none of the people in those planes were Iraqi, and because as a wounded nation, we gave a president, in effect, a blank check."
