Like most Americans, I get my news from the Daily Show. And so I was interested to learn that the whitehouse had posted "100 Things Americans Might Not Know About the Bush Administration Record"
The very first bullet point is:
Kept America Safe
For more than 7 years after 9/11 2001, prevented another attack on our homeland
Now, this kind of glosses over the fact that he kind of failed to prevent 9/11 in the first place, which is not really something that I personally would be bragging about if I were the departing president.
But it did occur to me that he was very, very effective in keeping America safe in many other ways, which, with typical modesty, he fails to cite.
