[net.politics] Ballistic Missile Defense

dand@tekigm.UUCP (Dan C. Duval) (09/07/84)

A point that I think many people are overlooking is that the military and
a number of politicians are not looking at Ballistic Missile Defense
(Star Wars) solely as a means to defend American cities from missile
attack but rather as a means of continuing the arms race.

BMD would have to be 100% efficient to provide any sort of credible defense
against a city-busting nuclear attack. Any less than 100% and cities will
go down. I might be willing to spend $500 billion to have Los Angeles and
New York nuked, but not to spend $500 billion on defense just to have them
nuked anyway.

If we look at the current situation from the point of view of the Air Force
brass, Star Wars looks much different. As the Soviets build more ICBMs, they
can allocate more warheads to each US silo and make their chance of success
against the entire US ICBM force better, especially since the US ICBM force
will probably have to ride out a surprise Soviet first strike (see John
Steinbrunner, "Launch Under Attack", Scientific American, Vol 250, No.1,
January, 1984:pp 37-47). The Air Force's job is to set things up so that
enough missiles survive that strike to retaliate against the Soviet Union,
thus keeping up their part of deterence. The traditional means of reducing
the Soviets' chances were to build more missiles and scatter the silos around
so that the same number of Soviet warheads have more targets they need to
cover.

However, with the debates going on about MX and the Midgetman, it is not clear
that the Air Force is going to get any more missiles in the near future, so
that day by day the chances of success of a first strike grow more in favor of
the Soviets. Someone then suggests a Ballistic Missile Defense.

Even if that system is only 50% efficient, it cuts in half the number of
warheads the Soviets can assign to each silo, increasing the chance of that
silo being operable for the retalitory strike. So suddenly, the Air Force has
a way to continue in the arms race without building any new missiles. Clever,
no?

I say, "no". It may be clever, but unless a 100% effecient BMD system can be
made, that BMD is there only to provide the US with a way to continue the
arms race without building any more politicly-unfavorable ICBMs. When the
missiles start to fall, the Air Force-operated BMD is not going to be used
to stop the missiles falling on US cities but rather to defend US silos so
that the destruction of the civilized world can be completed. The politicos
in favor of BMD should make it clear that this is a strategic MILITARY
weapon that continues the policy of Mutually Assured Destruction, not a
system to replace MAD.

Some say that the money desired now is seed money to decide if such a
system is feasible or not. If part of the $24billion Research and Development
money that the Army, Air Force, Navy, and Marines allocated in the
1984 budget (Armed Forces Journal, Vol 121 No 6, January 1984) is not being
used to study the feasibility of such a system, then the warplanners are
misusing those funds. Indeed, if such studies haven't been undertaken on
a regular basis since the first ICBMs, then our military and civilian leaders
have not been doing their jobs. I prefer to think that these people are not
stupid and that they are conscientious and that these studies have been
done regularly under existing and previous budgets, so we shouldn't need more
money for more studies unless there is a breakthrough they'd like to announce
to us.

My conclusion is, if we are not going to spend money on new missiles to
continue the arms race, we should not spend money on a BMD that is less than
100% efficient, for it is merely another way to continue the arms race. If
there is a 100% efficient BMD, then I need more information than what has been
published to convince me that it is feasible.

These views are not necessarily those of my employers.

Your scenario of the Air Force liking even a 50% effective
BMD system is quite correct, but you make it sound like
using BMD to protect silos is something the DoD is hiding.
Its not.  The first BMD system deployed will certainly not
have 100% effectiveness, or anywhere close enough to save our
cities ffrom a countervalue strike.  We shouldn't expect it to.
Protecting our silos is something I and many others see as vital
to the survival of our landd based ICBM force.  Note, BMD 
in this case is a fform of 'active' hardening.  Noone protests
when people propose improving the hardness off our silos
but scream bloody murder when you talk about using BMD to
to do the same thing.  Look, if you have a certain P(k) on
a silo, and you lower it by increasing its hardness, or lower
it by decreasing the number of incoming warheads, its still
lowered.  You seem to despise the idea of protecting our land based
missile force.  Do you really want them vulnerable?  BMD used
in this way is clearly stabilizing.  If you use BMD to protect
your most accurate heavily mirved missiles, there is no advantage
to having it in a first strike.  If we launched one, those
silos would be empty and would be protecting nothing.  If we
were attacked, it would increase the number of missiles 
surviving for a retaliatory strike.  

   You say this is expanding the arms race.  Well, quite 
frankly, what I'm cconcerned with is stability.  And having
a vulnerable land based missile force is destabilizing.  It
encourages the enemy to launch a strike since its so easy to
take them out.  By the same rationale, I would assume you
would be opposed to exchanged ICBM's for SLBM's.  You view
that as an expansion, even though the world is more stable 
afterward.  This is the same mentality of the freezniks.  They
want to stop everything, even systems that icrease stability.
I or one am not happy with the state of the world now, and
like to change it for the better instead of locking us in
to what we have now.  BMD will make the world much better
off.  People who think that you can somehow remove useful
weapons systems from the world's arsenals by signing some
piece of paper are really fooling themselves.  The issues
simply arent that simple.  We need to use reason when dealing
with problems like this, and not be motivated by hysterical
emotions...

Milo Medin writes that protecting land-based ICBMs is very important since
their so-called vulnerability means the Soviets are more likely to launch
a strike against them "because they're so easy to take out."

Look at this from the Soviet point of view.   We have submarines which we
are virtually certain they can't track.   Reason: we are ahead of the Soviets
in almost every important technology area and WE can't track them.  The
missiles on those submarines are enough to take out the 50 largest cities in
the USSR.  So of course they're going to launch a strike against our land-based
missiles, right?  What have the got to lose but their 50 largest cities?
Amazed they haven't done it already.

A complete lack of common sense seems to be a requirement for high positions
in the U.S. military-industrial complex.

Carl is right, it is implausible. It is also inconsistent.

To assume a Soviet leader would not be disuaded by the balance of
terror from launching a first "limited" strike and to assume that same
leader will confidently rely upon his American counterpart to be
dissuaded from retaliation by the balance the Soviet ignored is to
assume an irrational Soviet leadership. There is no defense against
irrationality.

Besides, even if a Soviet strike succeeded in wiping out US land-based
missiles, there is an available response which is approporiately
limited and therefore credible. An American leader need not respond by
launching a full retaliatory strike, but could instead launch a strike
against a few Soviet cities to bring casualties up to the same level.
Soviet leaders, even granted technical success, even assuming American
leaders would allow 10 million Americans to die rather than force the
Soviets into full retaliation, cannot put the US in the that dilemma.
The "limited" strike scenario assumes that the elimination of
land-based ICBM's would leave the US only two choices: surrender or
"unlimited" nuclear war. It doesn't hold water once other options are
recognized as available.

The real "limited" war scenario to be concerned about is not a strike
on US siloes, but on European cities. US threats to sacrifice Chicago
to avenge Hamburg may not be convincing to Soviet leaders.

David, you are missing sveral points:

1)  You talk about having to be irrational to launch a first
strike ignoring the balance of terror.  I hardly consider 93%
casulties for the US and 10% for the Soviets a balance of anything.

2) You talk about the US leader trying to launch a small strike
to equalize causlaities is impossible.  First, its really hard to
talk to submarines now, what makes you think you can talk to them
at all during a nuclear war.  It also takes about a hour or more
to transmit the EAM to the SLBM alert force via VLF, what kind
of adds are you willing to give that the few sites which can transmit
at that frequency are going to be intact after a USSR first strike?
This is why sub commanders can launch their missiles without the 
EAM, but how are they going to know what war plan to use?  Odds
are it'll be a spasmodic launch of everything if he launches at
all which is questionable.  


3)  Even if you lobbed all our SLBM force at the Russians in
a countervale strike, you will kill slightly more russians
percentage wise than the collateral damage to Americans of
a Soviet first strike (estimate of collateral damage = ~8%).

4)  I agree that putting US cities at risk to avenge NATO
country losses isnt credible.  Thats why the British and French
have their own nuclear forces.  And why we are deploying
pershing and cruise.  I am glad that you support that act at 
least.

In short, things arent nearly as simple as you make them out
to be.  The US and USSR are very dissimilar is population
distribution, strategic doctrine, and force structure, you
have to be very careful when making comparisons.

Also, a whole range of techincal issues are raised when operating
in a nuclear environment, the C^3 system we have is more
vulnerable than our ICBM force, but thank goodness the
present administration isnt ignoring C^3 like the past
several.  We are finally making major expenditures in C^3.

Soviet casualties will be far greater than 10%.  After perhaps a year,
allowing the more serious cases of radiation poisoning to die off,
Soviet casualties will run from 50-70%, while US casualties would
probably run from 75-90%.  The difference is due mostly to the greater
urbanization of the US rather than civil defense.  Moreover, the
destruction to Soviet infrastructure will be so great as to cause the
Soviet Union to cease existing as a unitary political entity, and this
is the best deterrent for a Soviet leader.

Time delays are of little concern; retribution can wait an hour, a day,
or a week.  Also, since we are speaking of a response to a LIMITED
nuclear strike, we are presuming that no warhead has landed on
Washington, and thus central authority remains intact.  A strike
taking out all VLF sites would not be limited, as this would require
strikes on the heavily populated Eastern seaboard (isn't one of the
sites in Maryland?).  Finally, even if the Soviets could take out all
communications between the submarine fleet and the US, they would NOT
do so if they intended a limited strike on land-based ICBM's,
especially if they were told that the fleet's default instructions
included launching everything if the commander is in doubt...

>3)  Even if you lobbed all our SLBM force at the Russians in

Whoa!  There are enough SL warheads to blanket every Soviet city with
a population greater than 50,000!  The SLBM force can, by itself, kill
nearly as many Russians as the entire nuclear force; what it can't do
is conduct a "surgical" strike, but I'm not interested in conducting
one. 

>4)  I agree that putting US cities at risk to avenge NATO
>country losses isnt credible.  Thats why the British and French

I support Cruise. I do not support Pershing, as their ability to reach
Soviet cities in less than ten minutes might cause a Soviet leader to
act rashly in a crisis.  Slowness in delivery, so long as it does not
make an attack ineffective, is a positive GOOD, not a liability.

There is still a tremendous problem with European deterrence.  The
West Germans are prohibited from deploying nuclear weapons, yet are
also the ones most threatened by Soviet attack.  If we aren't willing
to sacrifice Chicago for Hamburg, it probably follows that neither
Marseilles nor Liverpool are available for such service, either.  I'm
not satisfied that this problem has been solved.  It may not be soluble.

But it is ignoring conventional preparedness, unlike the Carter
administration. The dilemma in Europe is that our conventional
weakness may force us to go nuclear, and it is precisely because
Soviet doctrine differs from ours that we cannot be sure that nuclear
war can be contained.  I applaud expenditures on C^3, but not on most
of the nuclear arms programs.
