Lyndon Johnson actually said...
You children have a great and a very strong Nation--a Nation which wants nothing from any other nation on earth, but which earnestly wants all mankind to enjoy the blessings of freedom, of peace, of justice, of good health, of good education, of good jobs, of greater happiness and hope.
