""Mr. McNamara, You must never have read a history book. If you'd had, you'd know we weren't pawns of the Chinese or the Russians. McNamara, didn't you know that? Don't you understand that we have been fighting the Chinese for 1000 years? We were fighting for our independence. And we would fight to the last man. And we were determined to do so. And no amount of bombing, no amount of U.S. pressure would ever have stopped us." - Xuân Thuỷ, Foreign Minister of North Vietnam (1963 to 1965), during a 1995 meeting former US Secretary of Defense, serving from 1961 to 1968, Robert S. McNamara."
