Translation: The US DoD has been planning to have sole US military
access to space to the exclusion of all other nations it doen't like,
and when China shows its not going to be pushed around the US DoD
cries foul.

Rand Simberg: Utter nonsense.
Translation: we're going to treat space exactly the way we treat
the seas.
When exactly are we going to start doing that? (being honest and nice
that is)

BTW; there's all sorts of do-not-sail portions of our seas that are
currently fortified with our best DoD talent and resources. I don't
believe space is any different, especially the space that's directly or
near enough over American interest.

Chinese Shoot Down Satellite
http://us.cnn.com/2007/TECH/space/01/18/china.missile/index.html

All nations (including the all-knowing USofA) have the right of
terminating known spy satellites that are operating over their realm of
whatever can be seen or otherwise monitored from such nearby LEO space.

What I hadn't previously realized is that a given missile's horizontal
range is an indication as to accomplishing half that amount of range in
vertical travel, which makes North Korea entirely capable of clearing
out those pesky spy satellites as having been taking such unauthorised
look-sees at whatever they're up to. I'm certain we'd do the same of
taking out a North Korean spy satellite, especially were it in a LEO
path that made it capable of monitoring our every move.

I do believe that many of our spy satellites have operated near the 200
km mark, thus as little as a 400 km tactical field missile (perhaps one
of 500 km for good measure) should to do the trick. However, tracking
and obviously timing down to something better than a millisecond is
required unless the amount of explosive payload is rather substantial if
not thermal nuclear.

According to a spokesman for the National Security Council, the
ground-based, medium-range ballistic missile knocked an old
Chinese weather satellite from its orbit about 537 miles above
Earth. The missile carried a "kill vehicle" and destroyed the
satellite by ramming it.

This indicates that China has no apparent faults with their capably
tracking and essentially playing lethal touch tag with their own kind,
which obviously means they don't even require all that much explosive
energy, thereby making their efforts with less inert mass is certainly
fly-by-rocket efficient.

Actually, a retrograde impact would be rather impressive, though
extremely difficult to achieve.

I'm also fairly certain that quality SAR imaging via other than US spy
satellites has become doable by many of those capable of launching
scientific whatever missions. Their's may not be as good as ours, but
never the less, SAR imaging simply beats anything CCD optical by multi
fold, easpecially informative (nearly 3D) if obtained at 45 degrees.
