9/11 was the greatest thing to happen to Rudy Guiliani. If 9/11 hadn’t happened. He would have been remembered as a mediocre mayor at best. Instead he was mayor of NYC when the most devastating attack happened. And in that one moment he demonstrated strength. But that is his only claim to fame. As Joe Biden once said, “Rudy Guiliani, he only mentions 3 things in a sentence, a noun and a verb and 9/11.”
