Richard Nixon actually said...
When the time comes when the young in your land or our land lose their spirit of adventure, when they want to play everything safe, when they don't want to take the risks, when they don't want to take a chance, when they consult their fears rather than their hopes and their desires and their dreams, then your country and my country will not have the capability of greatness which you have in your country and which we hope we have in ours.
