The world knows that America will never start a war. This generation of Americans has had enough of war and hate... we want to build a world of peace where the weak are secure and the strong are just.

Let the word go forth from this time and place, to friend and foe alike, that the torch has been passed to a new generation of Americans - born in this century, tempered by war, disciplined by a hard and bitter peace.

It is an unfortunate fact that we can secure peace only by preparing for war.

Mankind must put an end to war - or war will put an end to mankind.

[Address before the United Nations, September 25 1961]

I've had enough publicity for 15 lives.

We have the power to make this the best generation of mankind in the history of the world or to make it the last.
