Actually, I think he brings up 9/11 in just about every speech. He did at the GOP convention.
You're right, he does. It is his standard stump speech.
Read the comment you were responding to professor:
He doesn't spend a lot of time talking about 9/11 in the speeches he gives.
Of course he brings it up. It was a major event in this nation's history and he presided over it. But like his book (which came out after 9/11) his speeches focus on the leadership strategies that brought NY back from the brink prior to 9/11. That's what schools and businesses pay to hear about, not war stories. Any good pulbic speaker adds segments to make what they are saying interesting, but no one would be paying that kind of money just to hear him re-hash 9/11.
