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?

If the planes can already deal with very high temperatures
over extended periods on much of their contact faces, why
would a laser (with the slight inevitable correction errors) be
able to do significant damage?
Yeah, this is a problem. This is one of the things that we would
expect the Russians to beat us at. Mirror surfaces too.
But everything has a limit heatwise. You push it past the limit.
Plus it is less than certain that all the electromagnetic spectrum
with any modulation whatsoever would not have any effect other than
heating.
The actual amount of energy required to vaporize the missles is
trivial. Problem is getting it there.
I never claimed that it would work against Russia. (At least not
recently.) But every weapon seems to eventually become obsolete.
They say now that they will quit building aircraft carriers, sitting
ducks for sophisticated folks it seems.
If the technical details can be solved, ICBM's are sitting
ballistic ducks. Shooting a beam of light is a heck of a lot cheaper
than launching an ICBM. In the limit, the ICBM is obsolete. A
sitting duck, just like the aircraft carrier.

Europe
Warns Bush of Global Warming ...... by THE ASSOCIATED
PRESS.......March 29, 2001 contains quite serious
language between allies:
"European officials warned President Bush
on Thursday that U.S. relations with the rest of the world could
suffer if he sticks by a decision to pull out of an agreement on
reducing global warming.
``This isn't some marginal environmental issue
that can be ignored or played down,'' European Union Environment
Commissioner Margot Wallstroem said at a news conference. ``It has
to do with trade and economics.'' > . . . . . .
While stressing it was too soon to discuss ``tactics to punish
the United States, Wallstroem said she will go to Washington next
week with an EU delegation to seek clarification of the Bush
administrations position.
. . . .
`` I dont think this is the time to start to
threaten, but we must be clear about the political implications,
Wallstroem said.
In diplomatic terms, that means that the threatening has started.
. . . . .
``It is not acceptable that national economic
worries mean that the world cannot act against a global threat,
said the Danish Minister of Energy and Environment, Svend Auken,
visibly angry.
British Environment Minister Michael Meacher also
warned of repercussions, although he ruled out the threat of
sanctions.
``I certainly dont think we should despair or try
to ostracize the U.S. as a pariah. This is not the end of the
story. There is clearly a power struggle going on in Washington
and we have to keep hammering on, he said.
. . . . .
`It would indicate the arrogance of power if the
United States were to discontinue the Kyoto process.
Are the critics in the wrong? Perhaps. But defenders of the Bush
administration, outside the US, were not cited, and may not have
legitimacy (or dominance) in any major country. In all events, this
language is not deferential to the United States.

German
Leader Questions Bush Plan .... by the Associated Press ..... March
29 recalls an impasse of substantially the same
starkness, discussed more decorously, but without even a whiff of
agreement, or even conciliation on substance, between Schroeder and
Bush.

I think we agree!
The project could be theoretically benefical as a defence given
three criteria:
a) The missiles makers don't deliberate make the missile to
withstand laser attack.
b) The system targets nearby missiles (dozens rather than
thousands of km).
c) We assume technology is sufficient (or advances sufficiently)
to allow this to be feasible.
The economic cost would need to be justified too. If it is
cheaper to topple every non-US aligned government in the world by
simple bribery ("The Dollars for Democracy Scheme"), we'd probably
be better off with the low-tech solution.
Do remember though, if the Korean were sufficiently dedicated,
(and unconcerned about diplomatic effects), it would be possible to
set off terrorist nuclear bomb in major cities, like NY. I'm
convinced it's morality, distaste at the method's diplomatic
reprocussions and fear of US reprisal that prevents the US's enemies
doing this right now. I doubt any western society, with current
social controls, could prevent it occurring.
I'm not saying the missile system isn't worthwile (despite the
above), but it's an umbrella that relies on rain from above, not
below.
Best Wishes,
Tom
