Nothing. You have a good point that needs further examination. It could be that nuclear weapons in space are too vulnerable to space based lasers, for example. Quite possible. For instance, it would be much more dificult to deploy and maintain the status of decoys, since the defensive systems will now have a long time to differentiate decoys from actual targets. You could also put KE weapons in close orbit, so you would not need the speed of lasers. KE weapons are also better at destroying decoys and target, since they can be used in a "shotgun" mode. If this is the case then those lasers should also be vulnerable to other lasers, so a defense dominated world would be highly unstable. This brings up a point I have not seen discussed, namely the heat sink problem (which is the limiting problem for defense against lasers). Battlestations could produce a lot of heat that cannot easily be carried away by convection (you would have to dump valuable mass overboard) or radiating (the fins would be very large, increasing vulnerability to attack).

They used a 747 simulator and tried several versions of possible pilot errors, such as a) forgetting to switch to inertial navigation b) Typos while programming the INS (transposing 2 digits of the coordinates of one waypoint comes close) c) skipping a waypoint The conclusion was that no *single* operator error provides an explanation of the actual course (a combination of 2 or more operator errors might explain it, but such a simulation has too many variables to be convincing). It was also noted that the pilots must have violated normal flight procedures: By the time the plane passed the last VOR in Alaska, the deviation from the normal course was already significant. The normal procedure required a check against the VOR which would have uncovered the problem. It was noted that the spy-community uses events like this to study the electronic signatures of the opponent's radars etc. and their intercept procedures. The bottom line of the Spiegel article is that both official stories (the one of the US and of the SU) have giant holes. ------------------------------ Date: Mon, 6 Jan 86 21:55:12 EST From: Herb Lin <LIN@MC.LCS.MIT.EDU> Subject: Putting a Man into the Loop From: Jim McGrath <J.JPM at Epic> After an attack is acknowledged, you concede the possibility of overkilling by the computer (taking out third party satellites and the like) in return for the more immediate response to attack provided by the computer. So your solution is that you kill everything, and don't do discrimination? No. I meant exactly what I said. You concede that you might make a mistake in firing (which was your original objection). Do you have your sources right? I don't think I said this... You do not aim for making a mistake. I explicitly said in the same message that one of the jobs of human operators is to assist in real time parameter adjustment so that the computer controlled weapons would be able to discriminate better. Why do you think the decoy discrimination problem is simply a matter of parameter adjustment? ------------------------------ Date: Mon, 6 Jan 86 22:02:07 EST From: Herb Lin <LIN@MC.LCS.MIT.EDU> Subject: The Goal of SDI From: Jim McGrath <J.JPM at Epic> From: Herb Lin <LIN@MC.LCS.MIT.EDU> We all, including the public, would like as high an X as possible, they would agree that losing a city or two and some missile bases/airfields would be a lot better than losing everything. But that is not the goal of the SDI. Which does not mean it should not be supported for that reason. Most government programs have consequences (sometimes good, sometimes bad) never conceived of in their initial purpose. That does not mean you ignore them when evaluating the program. My major problem is that I cannot make a case for SDI in the form of population defense *at all*, nor have I seen one made by you or anyone else. You are proceeding on the assumption that there is not a down side to SDI, and that's simply wrong. My technical argument against SDI essentially boils down to uncertainties about actual performance. These uncertainties have significant military and strategic implications, and they are mostly negative. Do you want to score points against Reagan and Company? Or do you want to discuss strategic defense, and SDI as it is developing? My objection to RR and SDI is NOT the research into SDI, but rather the shift of policy that seems to be accompanying SDI. It's as though the President announced a program of research to make people immortal, and proceeded to formulate policy on the basis of the expectation that the goal would indeed be reached. I don't really object to research into immortality, but to begin to abandon Social Security and retirement policies on the basis of expecting that people will soon become immortal, that's another question. ------------------------------ End of Arms-Discussion Digest *****************************

Most places in the world that need food will buy all the arms that they can get their hands on but not the food that they need. In other words, there is no market for excess American food among the starving third- world nations. Many countries have been known to sell the food that the U.S. sent as foreign aid (at below market rates) and use the money to buy arms (usually Eastern Block).

The most hyperbolic promises on behalf of SDI that I am aware of are by proponents. Last October 21 at MIT James Ionson of the SDIO repeated the old business about "if we have three levels which are at least 90% effective, then the total system will be 99% effective" (or whatever - maybe there were four layers). Reagan's views are on the record and are well known. A July 2 UPI story (Seattle PI, p. A2) quotes Weinberger, "A myopic focus on terminal defense can ... possibly lead us to mistake something less than total defense as sufficient for our requirements." What do you think he meant? How do you think the average person who listens to a news broadcast is supposed to interpret this? In fact, any system intended to defend populations from nuclear weapons really must be held to far stricter standards than any other defense system. Conventional defense (or hard-point nuclear defense) works by attrition: England won the Battle of Britain by knocking out 10% of each raid. Clearly, the Germans would have lost their whole air force before very much of London was destroyed, so they quit. On the other hand, a 75% effective nuclear defense is not very interesting, given the size of today's offensive arsenals. SDI proponents like to say "It needn't be 99.99% effective..." but never respond in the obvious way. Well, how about it? How effective does it have to be? Complete this sentence: "SDI won't be worth building unless it can stop at least X percent of the Soviet missile force." (Or, X percent per billion dollars. Or, any other metric of your choice). -Jonathan Jacky University of Washington ------------------------------ From: decvax!utzoo!henry@ucbvax.berkeley.edu Date: Sat, 12 Jul 86 01:21:15 edt Subject: Women, Science, and Nuclear Policy Richard Cowan writes: > ...The article focuses on the attitudes of female scientists who do not > wish to conform to male standards, and who therefore wish to transform > the current culture of science. My first reaction to this was "this sounds like sexist bigotry". My second reaction was "there is some point to it, but it *still* sounds like sexist bigotry". Most downtrodden groups (which women definitely are) claim to be noble, pure of heart, morally superior to their oppressors, etc etc. It seldom works out that way when they actually get a chance to take over. > It contrasts average women's attitudes > with the attitudes of the male policymakers who have brought us nuclear > pumped X-ray lasers and nuclear waste. This sentence still makes its point if you change "women's" to "people's" and delete "male" altogether, which makes the sex-based distinction dubious.

Perhaps > he would feel better if I had said "... are LIKELY to get." ... On the whole I agree with this, and with Don's further comments about investing resources in military preparations or peaceful coexistence. I would add a couple of reservations. One is the obvious problem with not preparing for war when your neighbor is busily doing so. The other is the case of Switzerland, which didn't get its peaceful reputation (and other related benefits, like surviving as an independent nation in the middle of Nazi-occupied Europe) by being unarmed or unprepared.

I would mind if 10 warheads exploded over Antartica. Perhaps not as much as 1 each on the 10 largest cities in the US. Or perhaps more because I prbably wouldn't be here to cope with the problems. It disturbs me when people dismiss the death and distruction relusting from the use of nuclear weapons. Richard Foy, Redondo Beach, CA The opinions I have expressed are the result of many years in the school of hard knocks. Thus they are my own. ------------------------------ From: decvax!utzoo!henry@ucbvax.berkeley.edu Date: Tue, 15 Jul 86 20:35:26 edt Subject: SDI and the ICBM threat Herb writes: > I beg to differ, but the Navy never said it would protect the > population against battleships... I'm sure if one had asked them at the right time, circa 1930 say, they would have been pleased to tell you about how they would protect the US coastline from attacks by foreign battle fleets. Battleships were primarily designed to fight other battleships, but they had a major shore-bombardment role too. (In fact, most of the shots fired in anger by US battleships in WW2 were against shore targets.) This is what "gunboat diplomacy" was all about, after all. > The difference between most > conventional weaponry and strategic nuclear missiles is that the > former are aimed at each other, while the latter are aimed at people. My recollection is that a lot of the current strategic nuclear missiles are at least supposedly aimed at each other. And conventional weapons do/did a lot of civilian-bashing too. > It is tolerable to have less than perfect defense against other > weapons, if you are trying to protect weapons. It isn't if you're > trying to protect people. Considering that virtually every defense system in history -- for an example, take British air defences circa 1940 -- has been imperfect, I see not the slightest shred of justification for this. An imperfect defence is intolerable only if you yourself happen to be on the receiving end of that part of the attack that it didn't stop. The vast majority of the population, i.e. the ones who got missed, will agree that it is very valuable and not at all intolerable. > If DoD said the goal of SDI were only to protect missiles, none of > this nonsense about perfect defense would be relevant... This is true but unrelated to the issue, which is whether perfection is a reasonable criterion for population defence. > I think it was McGeorge Bundy that said that 10 warheads on a modern > city would be a catastrophe beyond human comprehension, and even one > warhead would be a political blunder never before seen in human > history. This is rhetoric, not reasoning. I agree that it would be a tremendous disaster, although tremendous disasters are far from unknown in human history and do not appear to be "beyond human comprehension". By several reasonable criteria, the First World War was a far worse political blunder than a few warheads on one North American city would be. The later stages of World War II levelled virtually every German and Japanese city almost as thoroughly as a warhead or two would; today those two nations are among the world's greatest industrial powers. Ten warheads would be a disaster, yes... but it would be neither beyond human comprehension nor beyond our ability to cope. > I think 10 warheads would be utterly intolerable. It depends on what you mean by "tolerable". Considering alternatives like the utter destruction of Western civilization, hundreds of millions dead, and possibly a nuclear winter on top of it all, I would find 10 warheads eminently tolerable. Society would survive it, and any individual member of society (e.g. me) would have a high probability of surviving it. Not exactly an *attractive* prospect, but far superior to some alternatives.

Seriously, what bothers me most about SDI is that it attempts to solve what is essentially a POLITICAL problem with TECHNICAL means. This is compounded by the Reagan administration's demonstrated contempt for political solutions. It's much better to simply prevent the missiles from ever being fired than it is to attempt to construct untestable defenses which by their nature require a level of performance that most workers in the field publicly state is impossible to achieve. -- Larry Campbell The Boston Software Works, Inc.
