Bartlet v Nixon

In Series 3, episode 12 of The West Wing, Jed Bartlett gives his staff a motivational speech:

A president stood up. He said, "We will land a man on the moon in the next ten years." ... and we did it.

What Bartlett doesn't tell them is that President Nixon (for twas indeed he) was subsequently in receipt of a memo from speech-writer William Safire, outlining what he should say if that man did not come back. This surprisingly moving - if retrospectively-fictionalised - document can be read here, thanks to the splendid archival website Letters of Note.
