Reaching the moon before the "
hateful enemy" was simply a political move to keep the attention of the masses focused on something. Had it had a REAL meaning, the missions would have never stopped in 72. Ultimately useless, if not politically speaking. And speaking if political reasons means speaking of meaningless reasons by default.
Fact is, if you allow me this metaphor, when space travel is regarded we earthlings are still experimenting with oars powered canoes carved out of a tree trunk and/or rafts to reach a little cliff out of the sea right in front of our little island... and that happened how many times before those travels were abandoned? Five times? ...and lately we only used said canoes and rafts to circumnavigate our island, contenting ourselves to delegate farther travels only to bottles with a paper scroll inside because of the objectively unpractical long sailing times.
And unpractical long sailing times will remain until we invent at least the sails, or better yet some form of steam engine at the very least, around which build a real boat...
Do you see someone try to build said boat? Or its sails? Or its steam engine? Nope, too busy in other things, they still toy with canoes and rafts powered by oars, proudly calling them the cutting edge of today's technology... just like 40 years ago. Isn't that JUST great?

There is no such a thing as overkill. Only unworthy targets.
