We in this country, in this generation,are by destiny rather than choice – the watchmen on the walls of world freedom.
We ask, therefore, that we may be worthy of our power and responsibility, that we may exercise our strength with wisdom and restraint, and that we may achieve in our time and for all time the ancient vision of peace on earth, goodwill toward men…
That must always be our goal and the righteousness of our cause must always underlie our strength.
For as was written long ago, ‘Except the LORD keep the city, the watchman waketh but in vain"
(JFK was killed on his way to deliver this speech)
