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 thought the editorial was very good, but I'd modify or
supplement some words in it.
"Many more tests will be needed before a reliable ground-based
system is ready for use. These must include tests under more
realistic conditions, with the dummy warhead surrounded by multiple
decoys designed to draw the interceptor away from the target.
Saturday's test used a single decoy.
I'd add: The decoys should be realistic - -
they should be reasonably close to the decoys an adversary could
make for .1% of its missile development expenditure.
"This extended testing period should be used to try to
negotiate a new understanding with Russia
I'd add: Both sides should, ideally, consider
what the real risks and destabilizations are, and not stand too
much on operationally insignificant technicalities. The ABM treaty
should be robust in the ways that matter -- not brittle, to be
destroyed by actions that do not realistically involve real
changes in force balances.
"Boost-phase systems have some clear technological and
diplomatic advantages. They home in on an enemy missile when it is
still moving relatively slowly, is unlikely to be surrounded by
decoys and is trailed by a hot and bright plume of rocket exhaust.
The interceptor rockets, whether based on land or sea, would need to
be situated very close to the specific countries being defended
against and would pose no threat to the missile forces of other
countries, like Russia or China.
The editorial is discussing Richard Garwin's
close-in smart rock boost phase proposal, which is well within the
realm of the technically possible -- as gisterme and I
agree. (I made a limited apology to gisterme on this
subject.) .... MD6676 gisterme

"But these systems also have important drawbacks. The order to
fire interceptors would have to be issued almost immediately by
field commanders after an enemy missile launch, leaving little time
for consultation with Washington. Design and testing of a
boost-phase system would take many years.
Comment: These objections apply to any proposal
for missile defense. Missile defense is a quick-draw business by
nature. In my view, the Garwin proposal could be a working system,
offering some defense, sooner than anything else the US has at any
stage of development.
"Even if Moscow agrees to permit boost-phase testing,
Washington should continue its efforts to perfect a ground-based
system.
It should IF it has something that can work
on paper. Projects that can't work on paper don't merit huge
expenditures -- because they are hopeless.

I'd add something else. Theater missile defense, against short
range tactical missiles, is a different business from defense
against longer range missiles. We don't have the Patriot missile,
which should have worked in the Gulf war, working yet - because of
control problems. We should fix those control problems, and do other
possible things.
