Encryption Security The Military Transportation

Soaring, Cryptography, and Nuclear Weapons 303

Martin Hellman sends in a pointer to his essay that uses analogies from cryptography and the sport of soaring in an attempt to draw people in to thinking about the risks of nuclear weapons. Quoting: "... I did a preliminary risk analysis which indicates that relying on nuclear weapons for our security is thousands of times more dangerous than having a nuclear power plant built next to your home." Hellman is best known as co-inventor (with Diffie and Merkle) of public key cryptography, and has worked for over twenty-five years to reduce the threat posed by nuclear weapons. He is also a glider pilot with over 2,600 logged hours. Hellman adds, "Readers needing a break can go to some photos of the Sierra Nevada mountains taken from my glider."

    If the dangers from owning your own nukes are so serious, why haven't we destroyed the world yet - even with some of the so-called religious fundamentalist whackos that people are so afraid of in the White House?

    Honestly, all this fear running around and western democracies - and the Russians - are the ONLY ones who have managed them responsibly. We haven't blown the world up, and the worst are some "near misses" which didn't produce anything. Shoot, we're farther away now from nuclear war between major powers than we have been since before the Cold War.

    Point fingers at Iran, Pakistan, North Korea, and their ilk. Leave the rest of us out of it. They're the nuclear "powers" to be afraid of, and we should raise defenses against their armament which are overwhelming - not detente.

    Nuclear-armed nations invaded:
    Zero

    The US is nuclear-armed. The Mexican army has, on several occasions, gone into the US [washingtontimes.com] and threatened border patrol agents, helped drug runners, and other stuff. Certainly nothing large scale, that is true.

    The invasion of the US by illegal aliens from Mexico is a very large scale, and could form a fifth column

    And the reasonable environmentalists might be right. Technology might possibly have developed over the last 20+ years.
    We're afraid of technology that had flaws in its infancy. Maybe humanity has learned, and possibly improved technology since then?

    http://en.wikipedia.org/wiki/Richard_Jordan_Gatling [wikipedia.org]

    In 1877, he wrote: "It occurred to me that if I could invent a machine - a gun - which could by its rapidity of fire, enable one man to do as much battle duty as a hundred, that it would, to a large extent supersede the necessity of large armies, and consequently, exposure to battle and disease [would] be greatly diminished."

    Sounds a lot like this, from TFA:

    Since World War III would mean the end of civilization, no one would dare start it.

    The thing is, just as many bodies lie in the dirt since the invention of the machine gun, and armies are effectively as big as ever. Also, this invention has been used to commit COUNTLESS atrocities that wouldn't have been as possible before it was introduced.

    My point is simple, focusing on the WEAPON is futile. In the hands of men anything will eventually be turned to evil. You have to assume the worst case when dealing with weapons and humanity. This is also why you basically HAVE to participate in the arms race. The opposite choice is elimination.

    It's even worse than technology that had flaws in its infancy. Chernobyl is the only serious civilian power-generation reactor accident. And Chernobyl had a tremendously bad design that never would have been approved in the West, even in the period when everything nuclear was considered to be good, and what killed it was a horribly conceived experiment run by idiots that never would have been allowed in the West, again not even during that optimistic period.

    It's great to take lessons from Chernobyl, but it's wrong to take away the lesson that nuclear power is dangerous.

    there's this weird alien line of thought out there that goes like this: "if the usa has nukes, why shouldn't iran?"

    what that thought represents is tribal nationalistic thinking trumping common sense

    common sense holds that NO ONE should have nukes. so proliferation is bad, for whomever. the most logical approach to iranian proliferation then is this: "i am against iran having nukes, AND i am against the usa having nukes"

    but this whole "i support iran having nukes, to balance out the usa" is a level of stupidity beneath respect

    Strange risk analysis.

    Out of untold tens (hundreds?) of thousands of nuclear weapons, only 2 have ever been used on people, and that was at war time. Zero have gone off accidentaly.

    Out of the dozens (hundreds?) of nuclear power plants that have been build & torn down, there have been 1 major (Chernobyl) and 1 minor (Three Mile Island) accidents.

    That's a pretty small sample size to be dividing against a zero.

    I too wanna see how he produced that "risk analysis".

    Why would they? No country will use a nuclear weapon unless it's their last option. To do so would virtually guarantee total annihilation at the hands of the US. They would almost certainly use the nukes just like everyone else does: as a deterrent and as a bargaining chip.

    Clearly, it would put them in a much stronger negotiating position on the world stage. This is why we should be stopping them from getting nukes, not because we think they'd actually use them.

    The whole point of nuclear weapons is to overtly have them; if your possession of them is truly "covert," you don't win a damn thing. Even Israel's nuclear program was an open secret for years because it allowed them to gain the effects of deterrence without openly proclaiming that they had a nuclear arsenal. But nobody seriously believed they didn't have one.

    My understanding is that the ridiculously thick containment structure around the TMI reactor (the lack of which is one of Chernobyl's unforgivable flaws) would have saved the day anyway. And things have improved since then, my point was merely that it wasn't bad even to begin with.

    Waste becomes much less of a problem if you reprocess the fuel. We don't do that in the US because our nuclear policy is completely idiotic. But there's no rational reason not to do it.

    The general public seems to think that coal power is pretty acceptable, even though its toxic waste, vastly more than is ever produced by any nuclear plant, goes straight into the air and the population's lungs. But somehow the prospect of burying a miniscule amount of nuclear waste is considered to be vastly worse than breathing in vaporized mercury around the clock. It boggles the mind.

    fair enough, but what do you do once you are "against" iranian proliferation? John McCain (and many others) think that this means the U.S. should bomb Iran. I'm as against Iranian proliferation as I am against Korean, Bolivian, or Austrian nuclear proliferation -- but I am also against using phony claims of an imminent Iranian nuclear threat to justify hypocritical policy choices. If Iran does choose to go nuclear, that will be a decision that I have little influence on, and I'm not about to advocate bombing Iran to stop it. I'm more likely to advocate looking at how we all will manage to live in a world with an Iranian nuclear deterrent (and the reality is I think there will be a nuclear Iran eventually, though not nearly as quickly as the neocons want us to believe). I see no reason Iran would be any more irresponsible with its nuclear deterrent than India or Pakistan or China or any other member of the "nuclear club." The flip side of what you're saying is also true -- a nuclear Iran is a bad thing, but so is a nuclear Israel (or Russia or the US). There's no reason we should be more apeshit about a nuclear Iran than we are about any other nuclear state.

    I think, perhaps, the person you quoted meant invasions by the military forces of actual countries.

    It'd be more of an infiltration of the US by illegal aliens than an invasion. Invasions are rather obvious and hostile affairs.

    Non-state actors aren't the target of MAD policies. They generally don't care what sort of destruction they face. A state, on the other hand, has to worry about the continuance of the state.

    Psycho with a nuke: not deterred by MAD.
    Rogue state with a nuke: leaders still probably not deterred by MAD.
    Developed stable state with a nuclear arsenal: welcome to club MAD.

    Plus I'm quite sure most (by surface area) of the US would be quite willing (and eager) to sink both coasts into the ocean to quell a fifth column threat.

    The reason is that these countries are, ostensibly, sane, although I am beginning to wonder about Russia. Iran is ruled by a bunch of fanatics that believe in fairy tales and are attempting to bring about the return of the 12th Imam. The countries on your list have not used nukes, excepting the US pre-understaing-much-about-the-long-term-impact. We haven't since.

    Yes you're right the US is the only country that has ever used nukes, and though we haven't done so since, it's pretty clear the reason had nothing to do with restraint on the part of the United States -- it is well documented, for example, that Eisenhower and Nixon both considered using nuclear weapons in China and North Vietnam. So as far as using nukes, perceived "sanity" does not seem to be the major deterrent. In fact, the major deterrent seems to be nukes in the hands of our enemies. As far as whether Iran is "sane," I would suggest you look at what they've done, not just the idiotic religious rhetoric of the country's titular leaders. Iran simply has not behaved aggressively in international affairs. They have not invaded their neighbors despite their sabre-rattling towards Israel (though Iraq invaded Iran in 1980). The Iranian military is no joke, to be sure, and nukes will make it more powerful, but that is really a major concern only for anyone unwise enough to attempt to invade Iran. Pakistan's and India's governments are also filled with millenarian fundamentalists (and, hell, we've had quite a few of those in power here in the United States as well!) but the fact is that when the chips are down, these states have acted like states, and have not used their nuclear weapons "irrationally." I see no reason to believe Iran would.

    All that said, I am still against a nuclear Iran; I just don't think we can realistically do much more than we are already doing about it. Get the UN to castigate them, sure; encourage government reform, definitely; but if you think invading Iran is going to help anything you are living in an absurd fantasy land with John McCain.

    Context: stuff with a half life of 10,000 years

    I am being completely serious here. Any materials that last that long are more than safe enough. Heck, anything with a nuclear lifetime that long is safer than the Potassium stored in your body*.

    Think about it. Radiation is a process whereby mass is converted into energetic particles. Thus the mass itself is the fuel for the radioactivity. The more radiation produced, the faster the mass is converted into that radiation. In result, the mass will burn itself out in a short period of time. Materials with 10,000 year lifespans convert their mass to radiation so slowly that you can count each particle as it is produced. Compared to cosmic radiation, that's a zero risk.

    The fallacy in your reasoning is that if you have enough stuff with a 10,000 year half-life, even though its radioactivity-per-gram is low, total radioactivity can be high enough to cause health risks to nearby living creatures.

    One of the brightest moments for McCain in the debates (for me obviously) was when he said he supported nuclear fuel reprocessing. Obama isn't against nuclear in principle; I hope he will be open to the idea of reprocessing instead of letting the red herring issue of nuclear proliferation that caused Carter (a nuclear physicist!) to ban breeder reactors.

    The general public seems to think that coal power is pretty acceptable, even though its toxic waste, vastly more than is ever produced by any nuclear plant, goes straight into the air and the population's lungs. But somehow the prospect of burying a miniscule amount of nuclear waste is considered to be vastly worse than breathing in vaporized mercury around the clock. It boggles the mind.

    That's because of tremendous ignorance about even the basics of radiation, such as the longer the half life, the lower the radioactivity. And that while high levels of radiation are of course very bad, something with a half life of ten thousand years isn't necessarily more poisonous than something that isn't radioactive at all. Oh and of course there's the general fear-mongering of all things radioactive since the dawn of the atomic age, perpetuated by Hollywood myths where even in the distant future any nuclear reactor is a single leaky coolant pipe away from nuclear detonation.

    Whereas inhaling the byproducts of coal power plants has been an American tradition for over a century. So nobody thinks about how bad it really is.

    But zer whole point of ein... nuclear deterrent is wasted if you keep it a secret! Why didn't you tell zer whole world, eh?

    Secret nukes: bad idea. If your neighbour attacks you and you use nuclear weapons in self-defence, millions are dead. If you publish details of your armament to the world ahead of time, your neighbour never dares attack in the first place. Conversely, if you attack your neighbour with your secret arsenal, millions are dead and are rather surprised about it. If you publish ahead of time, your neighbour still can't do a damn thing to stop you that they wouldn't be doing anyway.

    The best policy with these weapons is to keep their development as secret as possible, but once you have a working deterrent, tell the world as publicly as possible. If word gets out that a nuclear capability is in development, the Americans or the Israelis will attack you, but if nobody finds out until after you have already tested a device, they won't dare.

    While you are correct that Chernobyl was a bad design and an ill-conceived experiment started the disaster, do you recall what caused Three Mile Island or what the consequences might have been had the hydrogen bubble ignited?

    The hydrogen bubble did ignite- several times. Several Containment building pressure spikes were noted from the repeated conflaguration of the hydrogen generated by the destroyed reactor core.

    Again, the containment building did it's job just fine. Further, reactors built after that accident had measures installed to mitigate the build-up of hydrogen.

    Of course, I wouldn't expect a whole lot of deep thought from someone who bases his handle on the hatred of a politician. That kind of obsession betrays the fact you have a few screws loose.

    ...do you recall what caused Three Mile Island...

    Three Mile Island was a success! No one died. The safety protocols in place worked. It led to no deaths or injuries to plant workers or members of the nearby community. Radiation levels to the surrounding population was about 1/6th of what would be received from a chest Xray.

    Stop treating TMI as if it were a disaster. It wasn't. Chernobyl on the other hand was, but NOT TMI!
