[Science and the world of tomorrow] What would Uncle Sam do about any satellite killing missiles?

I was at the home of one of the Brethren who likes watching lots of technical and history TV. One of the shows about technology had a segment about controlling the skies (mainly space), and alluded to the Chinese were trying to develop missiles that can be fired from Earth to take out satellites in LEO and MEO orbits. Seeing that fact can make a threat of one having such missiles, as they can take out spy satellites or disrupt weather satellites, if Uncle Sam discovers that the Chinese developed them, what would happen, would the US try to send spies or operatives to sabotage it? Maybe trump up some reason to bomb the instillations or get some fall guy (some affiliate) to do the actual dirty work? Would Uncle Sam try to steal the technology and arm themselves with like missiles, to retaliate should they be used against US satellites?
