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?

Why would any very complex level of AI be needed to track a
ballistic missile? As dirac says, the "B" in ICBM stands for
"sitting duck". ICBM payloads follow a nice parabolic trajectory
once the boost stage is over. Given the equation of the parabola and
the location of the warhead at a particular point in time one could
predict where the warhead would be 5 minutes hence by using a
hand-held calculator.
There is one thing that nobody has mentioned yet on this thread
and that is that not all intercontinental missiles are ballistic.
The Russians developed "sub orbital" weapons systems in the '70s as
an attempt to reduce warning time. Their trajectories are not nearly
as predictable as a ballistic missile. Still, dealing with
sub-orbitals should not be much more difficult than with ICBMs given
a space based real-time tracking system coupled to speed-of-light
intervention (read laser).
Don't see a need for any serious AI there, Robert. Do you?
WRT the "Hubble Wars" automobile headlight example (rshowalter
6/27/01 10:39am ):
"...The Space Telescope...has enough resolution to just tell
the difference between a car 2000 miles away facing the telescope
head on with one headlight, and a car with two headlights at a
distance of 2000 miles
Just tell the difference -- not get a clear picture -- that
means just be able to tell the difference between a single blur, and
two merged blurs..."
If you want to shoot the left headlight at 2,000 miles, Robert,
just aim the laser at the center of the left blur and hold it there.
Then pull the trigger. I wonder how many times brighter the infrared
signature of a rocket booster is than the optical signiture of an
automobile headlight? ICBMs are MUCH larger than cars.
I'd also assume that the headlight "blurs" could be better
resolved through the atmosphere by use of adaptive optics...and
another reasnable assumption might be that a space or aircraft based
laser would not be fired until the boost vehicle had cleared most of
the atmosphere. No point in doing EVERYTHING the hard way.

Gesterme,
What about guided "intelligent" and stealth missile quietly
dropped from the satelite?

NEW FAMILY OF RUSSIAN MISSILES WILL CREATE MAJOR PROBLEMS FOR
AIR-STRIKE PLANNING IN YEARS TO COME, SAYS LEADING DEFENCE EXPERT -
http://www.janes.com/press/pc000308.shtml
"Throughout the Kosovo War air campaign the major Russian
missile manufacturer Almaz Central Design Burueau was quietly
putting the finishing touches to a new family of highly effective
S-300 and S-400 surface-to-air (SAM) missile systems. Destined to
become widespread both inside and outside Russia, the presence of
these missiles will "create major problems for [air strike] planners
for years to come", and their significance has been greatly
underestimated by Defence Ministers worldwide. "

Noted (above) that Russian Engineering and Manufacturing would
like a slice of NATO's orderbook. For various reasons this might
not happen. Raises the point as to how the Russian economy might
otherwise utilise its peoples to produce regular product that IS
in demand. What regular products might be developed with added
value (increasing product demand). I'd see tourism as an area
that could be further exploited in exchange for foreign currency.
Foreign exchange is necessary, but, how much National
development can be made via local development. Pity Russia was
'stripped' by its own political mafia.

Great to have missiles .. but .. are they really a wasted
expenditure when other NEEDS have to be met for the people ?

The United States violated the rights of Germany and two of
its citizens when it denied the condemned brothers access to their
consulate before executing them in 1999 for murder, the World Court
ruled Wednesday. - http://www.newsday.com/ap/text/international/ap481.htm
The problem is not in this or that particular case. The problem
is in a MINDSET and the PATTERN.
As of Dirac, Midmoon and Gesterme - like, "The US CAN'T be guilty
of any wrongdoings. But, even if is, just ignore those
finger-pointers. We are the GREATEST, aren't we?";)

Just ask the Serbians after the 60bn and 3000 death
"humanitarian" bombing.
Can you calculate the relative size of such damage in US?

Does the world still have to plan huge defence systems ... is
land and territorial acquisition still the biggest external threat
to NationStates ?
