Who could have known?

Dowd

Why does this self-styled "can do" president always lapse into such lame "who could have known?" excuses.

Who on earth could have known that Osama bin Laden wanted to attack us by flying planes into buildings? Any official who bothered to read the trellis of pre-9/11 intelligence briefs.

Who on earth could have known that an American invasion of Iraq would spawn a brutal insurgency, terrorist recruiting boom and possible civil war? Any official who bothered to read the C.I.A.'s prewar reports.

Who on earth could have known that New Orleans's sinking levees were at risk from a strong hurricane? Anybody who bothered to read the endless warnings over the years about the Big Easy's uneasy fishbowl.
