As a long time disciple of Sagan I think we owe it to ourselves to explore the Universe. But what I don’t quite get is, as you’ve said so yourself, if we haven’t yet finished exploring the Moon and whatever possibilities it holds (or not. we simply don’t know for sure do we?) why place so many resources in exploring Mars? STM the allocation of resources for these endeavors should be based on solid science and not upsmanship.
Seriously, though I very much doubt I’ll see the day when the Moon appears as an option to Nuclear Holocaust, it is – or at least for as long as science tells us not – the closest scape route for those who can make it.

Well, I think that there is a sense of Been there Done that wrt the moon in much of the US publics/politicians minds. Also, Mars is an entire world with atmosphere, weather, and lots of interesting puzzles and such. The moon has no atmosphere and is much more geologically boring.
That said, the moon is also much easier to reach…which is why NASA is currently planning several unmanned and later manned missions back to the moon, both for exploration and for studies in logistics and extra-terrestrial engineering and habitat stuff. Of course, those programs will most likely get whacked by the next administration, so it’s hard to say. From other countries perspectives I think there is a sense that the US has already been to the moon, and following now would just be following in our foot steps (even if they did more and better science if they went), while going to Mars would be forging ahead. That’s why China plans (currently) to shoot for Mars sometime in the 20-teens IIRC…and why the European space agency and Japan are also looking at possible manned missions to Mars.
Myself, I think the moon is important as a next step to exploration of the solar system. It’s close. It’s (relatively) easier and less risky to get to. If it has water it will have all the elements needed to sustain human life, at least in the short term. It can be re-supplied from Earth relatively easy. There are still things to explore there, still interesting things to find and discover. It also makes a great stepping stone for further exploration…much less of a gravity well to launch from, rocket fuel can be made locally, would be easier to build and launch space ships from there (lower gravity but not zero gravity, so less stress on the humans). It would also help us learn how to build the structures we’d need to go to places like Mars and live there.
Lastly I think it would make a hell of a place to put something like the various stations we have in Antarctica for scientific research. Besides…the coolness factor for having a moon base is really off the scale. 
What I wish is that the US, Japan, the EU and perhaps Russia could get together to plan out and fund such an effort together, instead of having separate programs. Once a base on the moon is established I’d like to see them carry through with another unified program for manned and unmanned missions to Mars, Europa, etc etc…again, instead of everyone doing their own thing. Not going to hold my breath though…
