Weaponization of Space: Boom In A Vaccuum.

On my way into work, I listened to this [lame] radio program on weaponization of space [wiki]. I wonder what is good policy? Some key issues:

• Why do we need it? China blew up its own satellite [good article] last year and the US followed suit [good "article"] this year. We can clearly blow stuff up in space. A relatively cheap cruise missile can hit any point on earth. Isn't there a land-based missile shield already going up in the US and Poland? Can't we pretty much do everything we want already?
  
• Is it inevitable? [pdf] What do Star Wars, Star Trek, and Battle Star Galactica teach us? Exactly! Weapons in space are useless without attractive women in space--the so-called Guns-n-Babes Theorem. [babes] They also teach us that the future revolves around weapons in space.
  
• If maintaining America's status as the sole superpower is taken as a given (a separate decision), is that best accomplished by embracing a weaponization program that could begin an arms race we may or may not win? That may or may not damage the economy? Or is it better to discourage weaponization because, more than any other nation, our military and much of our economy are dependent on vulnerable space assets?
• Do you enter into arms control treaties that cannot be enforced? How do you inspect space weapons? How do you deal with dual use technologies--small "communications" satellites that are really kinetic kill vehicles?
