The Moon Landings took place during the Nixon administration. When the Soviet Union collapsed they found an experimental aircraft that looked like the Space Shuttle rusting in some hanger. The Space Shuttle program was cancelled during the Obama administration. Some day if Barry and his boys have their way somebody is going to find rusty Space Shuttles rusting away in some hanger in was was once known as the USA.
There wasn't a lot of strategic importance to landing on the moon past the initial PR win of getting there first. We eventually gave up on moon landings too. Until recently there just wasn't a reason to go, and even now the biggest reason is mostly theoretic (possibility of H3).
Plus, what we learned after the Cold War is that the Russian program was basically just a lot of crap tossed into space that may or may not come back. They weren't really that far into space exploration.
The Apollo program was one of the prime movers in getting computer science going. And the fact that one could view the event live all over the world as it happened were two very important accomplishments. And that is not even noting the psychological importance of the earthrise picture.
