The most significant accomplishment of the Apollo space program
was the clear public demonstration that the US has the rocket-booster
capacity to launch heavy nuclear warheads to any point on Earth, and
the navigational ability to place them precisely where we want them.

An incidental accomplishment of the program was a great boost to
US national pride by landing men on the moon for the first time ever,
and returning them safely to Earth.
