Ronald Reagan, October 27, 1964, in a speech he wrote himself:
You and I have a rendezvous with destiny. We will preserve for our children this, the last best hope of man on Earth, or we will sentence them to take the last step into a thousand years of darkness.
Featured here, in a campaign video for Barr ’08:

I’m going for a walk in the thunder.
