"What together we can do for the freedom of man?"

  Q:   Why the second part of the quote is rarely, if at all, quoted?

"And so, my fellow Americans:  ask not what your country can do for you - ask what you can do for your country.  My fellow citizens of the World:  ask not what America will do for you, but what together we can do for the freedom of man."

John F. Kennedy (1917 - 1963), Inaugural Address, January 20, 1961
