>> barry mccaffrey, please stay with us. we're joined now by tom brokaw, who covered george h.w. bush. tom, you wrote the book about george h.w. bush's generation, the greatest generation. he was the final president of the united states from that generation. >> he was. and i had a hard time persuading him to participate in that book. he was always so modest about his public service. and i finally said, you know, mr. president, this is your generation and you were so representative of it. and he reluctantly agreed. and then i remember one of the most vivid moments and proudest moments of my life on the dedication of the world war ii memorial in washington, d.c., he was seated just down from me on the podium and when the remarks from the various speakers were going on, he took off a piece of cardboard and wrote on it and said, dear tom, i think i was wrong, maybe we were the greatest generation. and then i developed a personal relationship with him through our mutual friend jim baker.
