BackgroundAs I'm sure everyone knows by now, Barack Obama has ordered the abandonment of the American Constellation rocket program, whose principal aim was the American return to the Moon (

You're assuming that spacecraft remain as relatively fragile and vulnerable as they are today, which would require a complete lack of progress in both hull materials and active defenses against micrometeors. I would be astonished if both conditions persisted a mere century.
When the resources returned exceed resources invested, when technologies bring profitable payoff, space travel will get flooded with commercialism just like everywhere else. In the mean time, until the energy efficiencies are there, it's a pretty lousy taxpayer boondoggle.
The problem is that, when that point is reached, if someone else has already gained control of the Moon, then that Power will reap the rewards, because they will have the infrastructure already in place. That this point will be reached is fairly predictable -- if we had deuterium-trihelium reactors, trihelium would already be cost-effective to mine from Lunar sources, and our astronautical ( ... )

I still like the Jupiter Direct idea of using Shuttle architecture already developed, but I guess that's not on the table.

Note that it is now the Democrats who are technologically regressive: compare with JFK and LBJ's original support of and Nixon and Ford's hostility toward NASA. The change really came with Bill Clinton.

They didn't replace it with any new manned spacecraft. In consequence, NASA will have no manned spaceflight capability for many years to come. They also didn't offer any alternative route for American Lunar exploration and settlement.

Note that the tri-helium reactions are much more energetic than the most probable boron reactions. Thus, barring something like femto-technology to let us queer the odds, tri-helium will be of vital importance as a fusion fuel.

It's not a question of nation-states. It's a question of cultures. The Western Roman Empire is some 1550 years in its grave, yet the Roman legacy profoundly influences practically every culture in the modern West. And, to take your example, while the Ottoman Empire is long gone, the Republic of Turkey is doing just fine. Nations long survive particular state incarnations.
Then you must consider the fragility of colonies. Most on Earth split from their parent sooner or later. Also most sci-fi predicts an independent Luna. I guess it seems too high-risk.
Only if all you care about is the future power of your state, as opposed to the future influence of your culture.
Obama's simply not capable of taking the long view.

Oh, and in the context of a future in which the Solar System is extensively colonized, eventually the colonial populations will grow to a combined total dwarfing that of the homeworld; they are likely to be far richer per capita than that of the homeworld within decades of their foundation. Thus, the future "globalization" is likely to come from offworld, past a certain point -- just as present-day "globalization" has originated largely from a Power founded in the New World, and it has been a very good thing for Britain that America considered her the Mother Country ( ... )
