Russian military leaders have expressed concern about US plans
for a national missile defense system. Will defense technology be
limited by possibilities for a strategic imbalance? Is this just SDI
all over again?

I am an engineer who works in the image processing pattern
recognition field (e.g. building software to automatically find
nasty objects in images). I started 15 years ago at General Dynamics
where my task was to find "camouflaged needles" in "camouflaged hay
stacks." One basic rule of thumb I learned was that if you can't
tell the difference between the decoy and real thing by eye then you
aren't going to make a computer program that works. The fact is that
millions of years of evolution has made any animal better at this
then any computer program. We used to joke that we could field the
"top" system by training a dog. The problem was how to disguise
feeding the dog in the maintenance manual. It isn't a question of
"do we have the will" or "we can do it if we set our minds to it
just like we sent a man to the moon" because, as anybody whose done
this kind of pattern recognition knows, making decoys is a trivial
way to thwart detection even in images of stationary targets let
alone ones moving at thousands of miles per hour. It isn't that
difficult to build decoy warheads, etc., that at all wavelengths of
the EM look like real ones (to any level measurable to sensors far
away w/r to ultra fast moving objects). The decoys will follow the
same trajectories as the real warheads so there's no additional
information that can be obtained from movement (and so detecting
decoys from real warheads isn't any easier than it is for stationary
decoys). Furthermore, NMD, as I understand it, isn't going to help
against cruise missiles. It won't defend against terrorism. The
thought of a terrorist with a small, low tech bio-weapon makes me
shudder. All in all, this discussion would be amusing if it wasn't
for the serious implications of spending that money, the arms race
it could create, and what it says about how our gov't makes its
decisions on technology (specifically, that its not based on the
science, just the politics). If this were technically feasible this
would still be an interesting debate. Given that it's not, it's just
mind bogglingly stupid.

"Robert Showalter showalte@macc.wisc.edu
New and more powerful weapons -- in the ways where military
utility means something -- are very close at hand -- with the new
vulnerabilities of the internet world. Nuclear weapons have become
obsolete -- liabilities, not assets."
a) Even though the US and its allies are getting increasingly
good at playing this international chess game of military force
application, a big solid club to smash the whole metaphoric chess
board is still relatively useful. That is why I would not go so far
as to call nuclear weapons "obsolete," they really aren't, yet.
b) You seem to consistently and persistently believe that our
nuclear weapons are vulnerable to hacker attack: THEY ARE NOT! All
of our launch codes, command & control systems are on
independent systems. There is next to no access for a hacker to
exploit. All a hacker can manage to do at this point is ruin
low-priority orders and pay schedules...which could make the US's
military flexibility a bit hamstrung, and if lucky, impact on morale
(no pay, and no snow muffs due to SNAFUed supply orders).
c) The point that you allude to, and I agree with, is this:
increasingly unconventional and unorthodox attacks are likely ...
posing little direct risk to life and livelihood that the military
is so well suited to dealing with. NMD/SDI does jack for protecting
the US from these sorts of attack...or the more violent
unconventional sorts (as McVeigh illustrated so well).

"(specifically, that its not based on the science, just the
politics)."
It is far, far worse than that. If it were truly based on
political decisions, than it would have to accept that NMD presents
a horrific strain on our political alliances and the domestic
political situation that has grown since the end of the Cold War.
No, IMHO, the decision is based on ignorance and
military-industrial calculations alone.

4/30/01 2:19pm Great stuff. And on top of the points you
mention, are problems of sheer resolution - all through the system.
Technically, Star Wars is crazy - - we, still today, have trouble
getting our air to air missiles to hit targets -- our best control
stuff is far worse what animals can do.

HELLO!! Now we know why W made his "bonehead" statements about
Taiwan, is antagonizing China, and snubbed South Korea on North
Korea talks - to generate yellow bogeymen and increase public
fear... and consequently support for SDI BOONDOGGLE. China &
N.Korea are only commie states capable of pointing missiles at us.
State Dept even said it doesn't HAVE to ACTUALLY be effective, just
SEEM to be effective so that prospective enemies will "lose
confidence". So in the spirit of leaving no oil baron or military
industrialist behind, let's pump out millions for worthless lasers
and other arcane equipment. In fact, why not get set designers from
Star Wars and other films to really make the junk look good, and
SPFX guys from The Matrix and (most apt) Wag the Dog to sell it to
us. (Meanwhile, terrorist walks over border with a bomb suitcase.) W
is about as big a concern to me as any nuclear disaster. It's been
100 days of worst right wing fears realized.

Whatever the problem of our government, domestic or foreign, BuSh
and his advisors seem to believe the solution lies in increasing the
wealth of the select few at the cost of the lives of the majority.
His missile defense project threatens another cold war. The only
certain beneficiaries will be the corporations which build the
so-called system. Other examples are numerous, eg., permitting
excessive CO2 emissions, terminating testing meat in school lunches,
reducing limitations of permissible amounts of arsenic in drinking
water.
Is this conservative compassion?
