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?

Some risks aren't worth taking. Because they can't be assessed,
and the penalties of very probable, or even certain mistakes
are prohibitive.

Complexity Powwow
"This past weekend I had the privilege of
attending the annual meeting of the various tribes of scientists
and science enthusiasts. The American Association for the
Advancement of Science .......
"Religious themes were everywhere in presence, if
mostly invisible and embedded in metaphors below the horizon, for
instance in Francis Collins' oft repeated "Book of Life" metaphor
and his explicit mention of non-reducible spiritual dimension of
human life. Stephen Jay Gould told the parable of Mary and Martha
in introducing the new AAAS president Mary Good ....
"In the many press briefings that I attended I was
struck that so much of the ground breaking work being done today
in the sciences involve highly interdisciplinary efforts (and
always the ubiquitous information technology specialists). The
subtext to the whole gathering was complexity and not just because
I don't always understand the technical aspects of atom-level
manipulations to create nanomachines or the pharmaceutical
implications of bioactive lipids. Rather, as Craig Venter noted in
his own talk, the interdisciplinary nature of many contemporary
scientific projects often leaves team members unable to "speak the
same language" as their colleagues. ....
"In one small seminar room, there was a powwow on
"Simulation, complexity, and ethics." There were presentations by
Sergio Sismondo from Queen's University, Stephen Batill from the
University of Notre Dame, Carl Mitchum at Colorado School of
Mines, Joe Berry from Stanford University, Bill Joy from Sun
Microsystems, and John Ilgen from Ilgen Simulation Techonologies.
Simulations are quickly becoming the tool for thinking through
science and engineering problems, but simulations are only as good
as the science and engineering of the selected variables.
There is a circular problem here. More over, these variables and
the algorithms of the simulations can fluctuate wildly in results
based on miniscule differences. Scientists, engineers,
economists, and policy makers often take these simulations too
literally, committing what A.N. Whitehead once labeled "the
fallacy of misplaced concreteness." It appears moreover that
we are quickly approaching an ethical crisis. Forget the debate
about utilitarian ethics, deontological ethics, or virtue ethics,
we are losing moral agency in our growing collective inability to
predict consequences of complex systems, for instance in the much
heralded genomic revolution. Nor will the precautionary principle
work, as the opportunity costs of doing nothing could themselves
be profound. As individual persons, we can still productively
talk about individual ethical behavior and duties, but in the
increasingly important distributed space of 21st century
technoculture, we just don't have the foggiest idea what is around
the bend. "
The unpredictability of simulation casts doubt on ALL the
simulations in the field of nuclear strategy and tactics, and a
detailed consideration of most of them would essentially remove any
validity they could claim.
In complicated circumstances, people using simulation make many
mistakes. In the nuclear weapons field, we know that "mistakes"
could destroy the world.
The risks associated with nuclear weapons, and strategies that
commit to them, are not worth taking.

Analysis: Russia May Help Persuade North Korea to Give Up Missiles
...By PATRICK E. TYLER
" . . . .from the South Korean perspective," he
continued, "it was inevitable for Kim to go along with Putin
because in return, Putin is working very hard to convince Kim Jong
Il to give up this missile program."
"Russia may have had its own game to play
internationally by enlisting Mr. Kim in the ranks of European and
Asia countries who hope America's missile-defense program will be
scaled back or deferred as arms-control regimes become more
effective and the missile threat subsides.
