SARAH PALIN: In what respect, Charlie? GIBSON: The Bush -- well, what do you -- what do you interpret it to be?
PALIN: His world view.
GIBSON: No, the Bush doctrine, enunciated September 2002, before the Iraq war.
PALIN: I believe that what President Bush has attempted to do is rid this world of Islamic extremism, terrorists who are hell bent on destroying our nation. There have been blunders along the way, though. There have been mistakes made. And with new leadership, and that's the beauty of American elections, of course, and democracy, is with new leadership comes opportunity to do things better.
GIBSON: The Bush doctrine, as I understand it, is that we have the right of anticipatory self-defense, that we have the right to a preemptive strike against any other country that we think is going to attack us.
