"Without his strong leadership, we would already have been attacked more than once since 9-11 . . ."
Maybe? Or maybe, if you're an AQ leader who can pull the trigger, you've decided not to risk uniting the civilized world at the present time?
We weren't attacked not because Al Qaeda wasn't trying -- but because we were able to foil their attacks.
Perhaps because they saw what happened under George W. Bush's leadership when the world united against them before, hmmm?
