This Friday marks the 50th anniversary of the assassination of President John Fitzgerald Kennedy. For those of us old enough to remember, it was a moment frozen in time, much like 9/11. JFK was supposed to deliver a speech in Dallas the night that he was assassinated.

According to an article by Paige Lavender on huffingtonpost.com, here are the haunting last lines of the speech that President Kennedy was to deliver that night in Dallas.

"Neither the fanatics nor the faint-hearted are needed. And our duty as a Party is not to our Party alone, but to the nation, and, indeed, to all mankind. Our duty is not merely the preservation of political power but the preservation of peace and freedom.

So let us not be petty when our cause is so great. Let us not quarrel amongst ourselves when our Nation's future is at stake.

Let us stand together with renewed confidence in our cause -- united in our heritage of the past and our hopes for the future -- and determined that this land we love shall lead all mankind into new frontiers of peace and abundance."
