If you had told most Americans, including me, on Sept. 12 that we would go thru five Christmases and five New Year's Eves...five sets of bowl games...five World Series...two major political conventions...and more....and that all of that would happen without an attack on the U.S., I think most of us would have said, 'no way.'
But look at us now.
It certainly could change and there are other factors to consider like the patience of the enemy (and they are patient), but I believe the president is a huge reason why we've been as safe as we've been for as long as we've been.
