If you combine your two points together, you realize that to track anything with a non-changing orbit, you just have to have to detect it once. And since everything is strictly line of sight, if you've been overflown by a satellite (spied on), then you've also had an opportunity to track the satellite and now know when the next fly-over / where will be. What the US has the potential ability to real-time track every satellite around the entire world. In fact, we're pretty sure that that capability exists because they've also tracked everything in orbit larger than a screw. While the X-37 has the capability to make some countries nervous, honestly space does have its own (weaker) version of MAD. I mean, if anyone does something stupid, then the rest can ruin it for everyone. I mean, do you think the US would go about laying mines in space when Russia/China probably have (will have) the capability to knock down GPS satellites? I mean, everyone knows where they are, everyone has the capability to insert into the same orbit. The US would be beyond stupid to use the X37 for anything other than recon (spying!), or grabbing it's own satellites/payloads. Anything else would been as dumb as co-locating satellite launch sites with ICBM silos. Also, despite the lack of public information given out by the Air Force and government, it's entirely likely that the Chinese and Russians know a lot more about the hardware and its capabilities than Wired and the public. Spy agencies exist for a reason. Even amongst 'friends'.
