Let every nation know, whether it wishes us well or ill, that we shall pay any price, bear any burden, meet any hardship, support any friend, oppose any foe to assure the survival and the success of liberty.

The mere absence of war is not peace.

The courage of life is often a less dramatic spectacle than the courage of a final moment; but it is no less a magnificent mixture of triumph and tragedy.

Aggressive conduct, if allowed to go unchecked and unchallenged, ultimately leads to war.

There is, in addition to a courage with which men die; a courage by which men must live.

Mankind must put an end to war before war puts an end to mankind.

Don't ask 'Why', ask instead, 'Why not'.
