Uh, note that we have experimental proof that the problem is solvable:
Ted Molczan plus a handful of other amateurs, with no government support,
have *done* it. Speculatation about real and imaginary difficulties is
silly; it's definitely known to be possible.
(At the time of the Gulf War, I was on the board of the Canadian Space
Society, and the CSS was running a small BBS that was then the main data
distribution point for the amateur spysat trackers. Ted asked us whether
he should suspend data releases for the duration. I don't remember what
we decided -- the data wouldn't be all that hard for others to duplicate,
and there was legitimate public interest in it at the time, so there were
arguments against a suspension as well as for it -- but it was a real and
Molczan's observers occasionally lose birds that have apparently
maneuvered into higher orbits, but a big satellite in low orbit is hard to
lose track of permanently.

The launch times are secret only before launch -- it is quite impossible
to keep a launch secret while it's happening. In particular, the spysats
would mostly be launched from Vandenberg, for polar orbit, and launches
from Vandenberg pass offshore of Los Angeles; unless the weather is bad,
literally millions of people can estimate the launch time within a few

Rogue nations can, and do, have embassies and less-conspicuous unofficial
representatives elsewhere in the world.
