John Kennedy actually said...
But if you share the view that I hold very vigorously, that this country is going to have to do better in the future, that we have responsibilities to meet not only to ourselves but to the cause of freedom, that we are anxious to make sure that in the future people decide that these days were great days in the life of our country, that we must move forward, we must stimulate our growth, we must hold out an image to the world of a vigorous, dynamic society, if we are going to continue to lead the free world - I believe that is the choice.
