NEW YORK-It only lasted a few seconds, but on May 17 George W. Bush had a Bill Clinton moment, and it was magical. "Had I known that the enemy was going to use airplanes to kill on that fateful morning," George W. Bush reassured us, "I would have done everything in my power to protect the American people." Did he realize how much he sounded like his prevaricating predecessor? Were the subject something other than the murder of 3,000 innocent people, such desperate dissembling would be absolutely hilarious.
