June 15—At this time of extreme world peril of the threat of nuclear war, the words that President John F. Kennedy gave at presentations on many occasions 60 years ago, ring true with guidance and inspiration in the anniversary year of his heinous assassination. On Sept. 10, 1963, when he addressed the United Nations General Assembly, he spoke of how, among all weapons, the “power of peaceful cooperation” is the strongest. He spoke of nations together having “agreements which spring from our mutual interest.”
