"Unable to defeat our enemy or break his will – at least without a huge, long and ever more costly effort – we must actively seek a peaceful settlement." b. "Over many years, we have made a national pledge to help South Viet-Nam defend its independence. And I intend to keep that promise." c. "We will not be defeated. We will not grow tired. We will not withdraw, either openly or under the cloak of a meaningless agreement." d.
