"When our astronauts returned safely to earth last Friday, the whole world rejoiced with us. We could have had no more eloquent demonstration of a profound truth--that the greatest force working for peace in the world today is the fact that men and women everywhere, regardless of differences in race, religion, nationality, or political philosophy, value the life of a human being. We were as one as we thought of those brave men, their wives, their children, their parents. The death of a single man in war, whether he is an American, a South Vietnamese, a Vietcong, or a North Vietnamese, is a human tragedy. That is why we want to end this war and achieve a just peace. We call upon our adversaries to join us in working at the conference table toward that goal. No Presidential statement on Vietnam would be complete without an expression of our concern for the fate of the American prisoners of war. The callous exploitation of the anxieties and anguish of the parents, the wives, the children of these brave men, as negotiating pawns, is an unforgivable breach of the elementary rules of conduct between civilized peoples. We shall continue to make every possible effort to get Hanoi to provide information on the whereabouts of all prisoners, to allow them to communicate with their families, to permit inspection of prisoners-of-war camps, and to provide for the early release of at least the sick and the wounded. My fellow Americans, 5 years ago American combat troops were first sent to Vietnam. The war since that time has been the longest and one of the most costly and difficult conflicts in our history."
