Never have the nations of the world had so much to lose, or so much to gain. Together we shall save our planet, or together we shall perish in its flames. Save it we can — and save it we must — and then we shall earn the eternal thanks of mankind and, as peacemakers, the eternal blessings of God.

John F. Kennedy (1917-1963) US President (1961-63)

Speech, United Nations (20 Sep 1963)
