I know many of you trashed the Taibbi piece but this is the only place I've seen this info:
"Clark elicited a similar response at the same press conference when he made one of the more cryptic--and in retrospect, one of the more meaningful--statements of his campaign. "The legacy of Vietnam," he said, "will be put to rest by the legacy of Iraq."

Buck rolled his eyes. "Oh, come on," he said. Then he elaborated. In Vietnam, Buck said, we had no strategy for going in and winning. In Iraq, we have the opportunity to "be successful."
"And success means winning, not withdrawing?" I said.
"Success means winning," he said. "He's made no secret about that."
I asked Buck if this was not exactly the same position that Richard Nixon ran on, vis-à-vis Vietnam, in 1968--peace with honor. A far from unreasonable question, given that Clark, back in those very days, during his studies at Oxford, had given speeches abroad in support of the Vietnam war effort. Also not unreasonable because Clark voted for Nixon. But Buck shook his head.
