David Weigel | August 30, 2006
In response to my Stanley Kurtz post, I've been getting a lot of e-mails like this.
Weigel has not explained how he would propose to "stop" a ballistic
missile from JihadLand to NYC. Only a ballistic missile has a 6000-mile
trajectory, and as far as I know, there is no operational ballistic
missile defense for the east coast of the USA against a transatlantic
attack. [There _is_ a nominal BMD on the USA west coast.]
From Navy Times:
By the end of the year, the Navy will have a total of six warships capable of tracking and shooting down ballistic missiles.
Three cruisers -- Shiloh, Lake Erie and Port Royal -- already have the capability to track ballistic missiles with upgraded Aegis radar. They also have the ability to hit a ballistic missile with an SM-3 missile, shot out of standard Navy vertical launch system tubes.
By year's end, the destroyers Stethem, Decatur and Curtis Wilbur will also have ballistic-missile defense capability, according to Lt. Tommy Crosby, a Navy spokesman at the Pentagon.
The ships patrol the Pacific right now, but I have no trouble believing they'd be redeployed to the Atlantic if we found ourselves in Kurtz's future world, where Iran flings around nukes willy-nilly and soylent green is made out of people. Remember that Kurtz's nightmare scenario - the one more dangerous than the Cold War - involved a rogue power firing a single nuke at the United States. I doubt we'll soon develop the sort of missile defense that could have neutralized a MAD-style situation with thousands of nukes. But one nuke?

"I doubt we'll soon develop the sort of missile defense that
could have neutralized a MAD-style situation with thousands of
nukes. But one nuke?"
I think we can but the question is will we? The Democrats in
Congress had kittens when Bush walked out of the ABM treaty. There
are significant portions of the body politic who are dead set
against missile defense. Many of the "we can live with a nuclear
Iran" crowd is also part of the "we must bring back the ABM treaty"
crowd.
Why on earth would they shoot a missile at us, when it would be so much easier to smuggle one in. This would also give them at least a chance at deniability (all it would take for the UN to oppose any US response, FWIW).
I don't know if it is that easy to smuggle one into the U.S. First, nuclear technology is not all created equal. If and when Iran builds a bomb, it will be of a crude fission type that ways in the 1000s of pounds. There is a big difference between building that and the small warheads the U.S. Soviets built in the 70s and 80s and even those are bigger than you think; the whole suitcase nuke thing is a bit of a myth. Further, getting it in the country is harder than you think. It is not like you can FEDEX the thing or strap to the back of some illegal alien coming across the Rio Grand. It would have to be in a container ship. It couldn't come directly from Iran. It would have to be shipped through a third party. Further, these things are hard to build and are really valuable. It would be a very bad deal if the thing was discovered in rout. I am not saying it is impossible, but I don't think smuggling one in is as easy as most people perceive.
As I said before:
There will never ever be an effective missile defense, for one
simple reason. However good our missile defense is, it can be
defeated for one one-thousandth the cost to us. So if we throw a
Trillion dollars into satellites, seismographs, and smart bullets,
a mere Billion dollars worth of balloons, confetti and noisemakers,
could slip a nuke right past it all.
What? Soylent Green is people? I think I'm going to be
sick.
I'm not sure that I understand all of the opposition to a missile
defense system. It makes some sense, particularly for shooting down
conventional missiles. As for nukes, it would be a shame
if a single missile were launched and we couldn't do anything about
it, wouldn't it? However, I agree that a complete missile shield
would be too expensive and probably vulnerable to workarounds (like
just smuggling your nuke to your location of choice) as things
stand today.
The advantage to a missile defense shield is that it would give the U.S. an option besides just murdering an entire country. If Iran or North Korea goes insane and launches a missile, the U.S. would have no other choice but to launch a massive nuclear retaliation. If the U.S. didn't do that, its nuclear deterence would be rendered usless and it would be open season on U.S. cities. That would be an unimaginable tragedy. I would prefer not to see Iran wiped off the earth. If the U.S. shot a missile and it landed harmlessly in the Atlantic, it would then not have to retaliate. I can't see how giving the country an option besides murdering millions of people could be a bad thing.
Despite the likelihood of work-arounds, it's the sort of idea
that is worthy of continued effort. As PL said, if we ever do need
it we'll REALLY need it.
That's not to say that we should jump on board with any particular
design (as Warren points out, there are a lot of work-arounds) but
it's not the sort of idea that we should completely give up on
either. There are a few crazy ideas that are worth pursuing, a few
impossible dreams that are worth dreaming. The ability to shoot
down a nuclear missile is one of them.
Nuclear non-proliferation is another crazy idea that is nonetheless
worth pursuing. I consider non-proliferation a crazy idea in the
long term, since I find it hard to believe that any really potent
technology can exist forever without eventually spreading and being
used. But given the stakes on this one it's better to try anyway,
and at the very least go to the mass grave of the future with some
amount of honor.
(Sobering thought: What if this is the reason why we aren't
receiving any radio signals from alien civilizations? Any
civilization smart enough to master electromagnetism can eventually
figure out how nuclear energy works.)
Smuggling a weapon, large or small, would not be easy, but it
would be nowhere near as hard as building an ICBM. You don't even
have to unload the ship, just detonate as soon as you're in the
harbour.
As R C Dean points out, it also has the advantage of deniability.
Much of the evidence would have been vaporized.
In terms of (no) bang for your buck, the money for missile defense
would be better spent on improved inspection, preferrably done
offshore. (The farther offshore the better, due to the likely
production of radioactive isotopes of sodium from the salt in the
seawater.)
The bomb doesn't have to be particularly efficient, either. The 1.5
kiloton explosion in Halifax in 1917 killed 1600 people, and that's
without a radioactive effect.
Finally, any nation that actually did launch a nuclear missile at
the US is going to get a regime change, whether or not the nuke
gets through. Even the French, Russians and Chinese would be on the
US side in that scenario.
Developing a way to intercept ICBM's will, of course, cause a
change in a potential enemy's tactics. The same could be said for
having a massive, high-tech, first-world standing army.
After all, if the enemy wouldn't stand a chance on a battlefield
with remotely-guided cruise missles, smart-munitions, Abrams tanks
and foot soldiers carrying night vision devices it would be pure
idiocy for them not to change their tactics.
However, claiming that we shouldn't build a missile defense system
because it will just result in the Bad Guys�� changing their
tactics seems kind of silly. After all, that's been the driving
development behind all of war since the beginning.
Still, I think that David is being perhaps a bit overly optimistic
about our abilities to intercept ICBM's now.
Defense
Tech certainly isn't all warm 'n' fuzzy about our current
capabilities, nor does this
timeline of missile defense tests do much to convince me that
we'd be able to intercept a missile.
On the other hand, I think that the reports of Iran's nuclear
capabilities are overblown (HA!) so there is a silver lining to
that cloud.
As I said before:
There will never ever be an effective missile defense...
If there will never be an effective missile defense, how come the
Soviets didn't want us to conduct research in missile defense?
This would also give them at least a chance at deniability
...
I wonder what we would/should do if there was a nuclear explosion
on American soil, and there were no claims of responsibilty and
really no strong evidence as to who was responsible.
I guess it wouldn't really need to be a nuclear explosion at all.
After 9/11 the imediate thought for most was that radical Islamic
crazies had done it. However, the initial reaction to the Oklahoma
City bombing was that it was Islamic crazies as well, but it turns
out that it wasn't. We were able to gather enough evidence to
conclude that Al-Qaeda was responsible for 9/11. (Assuming you
don't believe conspiricy theories)
What if it hadn't been so clear? What do we do if we're not so sure
who has attacked us? What if there had been significantly less
evidence leaning towards Al-Qaeda responsibilty for 9/11? Do we
still attack Afghanistan? Decide not to attack anyone? Blame Iraq
and invade them, just to be safe?
My hunch is that if the attack is devastating enough we will find
someone's ass to kick. Even if it isn't necessarily the
right ass.
FWIW, to follow up on John's point about suitcase nukes, this
article is a good read:
The
myth of "suitcase nukes."
TheDumbFish,
Nuke the moon, man, nuke the moon. There's a heightened deterrent
effect in just seeming a little crazy at times. "Whoa, that
America--better not let anyone nuke them, 'cause they're friggin'
nuts. No tellin' what they'd do."
There's always the Don Corleone Theory of Deterrence, too. We could
just tell Iran that if any U.S. cities go up in a cloud of dust,
even if it was because of an asteroid pegging the city, we
automatically will blame Iran for it. Ditto North Korea, I
suppose.
The advantage to a missile defense shield is that it would
give the U.S. an option besides just murdering an entire
country.
The disadvantage is that it doesn't work.
And just because the Navy says that in a year or so it will,
doesn't make it so.
Hey, I agree - a missile defense system, especially if we could
keep it to ourselves, would be peachy. Even better if we could each
get a pony with it.
But you aren't speaking from the reality-based world if you are
imagining that the capacity exists now or in the near future. If
you are going to base your foreign policy on this fantasy, then you
ought to at least make sure you have a backup plan. You know, just
in case.
Further, getting it in the country is harder than you think.....
It would have to be in a container ship. It couldn't come directly
from Iran. It would have to be shipped through a third party.
Further, these things are hard to build and are really valuable....
Sayeth John.
! Lessee....a nuke would be harder to smuggle, via various ships
& ports, than building a ICBM which by neccessity leave a
breadcrumb trail top its point of origin. 10's of millions of
containers, 10's of thousands of ships. Nahhh. Itll never happen.
And then theres the odd notion they are too valuable to ship, but
not too valuable to put on a dodgy rocket.
While the missile interceptor tech is fun, its simply a scam, a
wealth transfer racket. It dosnt even have to work- "bugs", bad
weather, the beacon/homing device on the target goes out....how
that old saw go: "Give us another couple billion & we'll move
this bomber a couple of feet". And then theres: "Heres a
contribution to your campaign, Congressman"- a few % more overhead,
if that much.
Meanwhile, the USCG, a front line outfit for any ACTUAL national
defense, continues to get its budgets cut, its requirements put
off, its replacement ships &equipment delayed. THAT tells you
all you need to know about these welfare queens & national
security.

thoreau:
Earth's had a really bright EM signal for, what, 70 years? I doubt
it will remain that way for long; new technology (ultra-wideband,
for example) will decrease our radio emissions, eventually to the
point not terribly past background. I give a civilization 500 years
as a radio bright object. As for intentional broadcasting --
they're all probably perpetually war with other alien civilizations
and don't want to reveal their location.
T Bone-
Good point about the likelihood of diminished radio
transmissions.
I feel that this line of discussion would benefit from the input of
PL.
Am I dumb in thinking that a single fighter jet could take out a
single missle? The only problem would be convincing a pilot to give
his life to save millions. I think someone would raise his hand. If
not, maybe we don't deserve to live anyway.
Just fly up alongside and let it have it. Wouldn't this work?
Ethan:
It would depend on the type of missile. A jet fighter could fly up
alongside a cruise missile but not a ballistic missile. Cruise
missiles generally fly at subsonic speeds close to the ground.
Ballistic missiles fly into space and back down. Trying to manuever
a jet fighter to be in the same place and time as a ballistic
missile would be extremely difficult. It would also only be
possible during the early boost phase and the late re-entry
phase.
Fine Tim,
Let's not spend a dime and just murder every Iranian in Iran. It
seems like a stretch to say that it is not "reality based" to think
that we could build a system that would have a reasonable chance of
shooting down a few missiles. Granted, you are never going to stop
a 20,000 missile Soviet barrage. But, how is the system not being
fullproof an argument against it? Lets say that the system only has
a 25% chance of successfully stopping a missile. 25% sounds a hell
of a lot better than zero. Further, in a country that is so rich is
can waste billions every year in pork, it seems to me to be a
pretty stupid idea not to be willing to spend a few billion for
even a 25% chance of saving literally tens of thousands of innocent
lives, to say nothing of the millions that the U.S. would kill in
retaliation.
Well, between civilizations collapsing quickly--perhaps not even
making it to radio capability at all--and a likely quick transition
from radio to other means of signal transmission, it's little
wonder that we're not picking up much. Not to mention that we
really haven't been looking that long or that thoroughly. And, of
course, it all depends on how frequently intelligent civilizations
develop. When I'm in a good mood, my calculation of the Drake
equation gives a high "N". When I'm feeling pessimistic, I
calculate N to be zero. Hey, I said that happens when I'm
pessimistic, didn't I? :)
From what we've observed so far, I'm willing to bet that life
arises quite easily and universally. Intelligence may be a
phenomenon that occurs much more rarely--no way to know for sure
just yet. Add to that the fact that we can't detect
nontechnological civilizations, even if they are godlike in
intelligence, and you get an even murkier idea of what is going
on.
Throwing reason out the window and extrapolating too much, I think
from our lone example that we'll find technological civilizations
to be relatively common. There's nothing obviously nonaverage about
Sol or Earth, unless Asimov is right, and we're the only planet in
the habitable zone with a large moon :) If I were a betting man,
I'd say that we'll hit the jackpot with SETI, Optical SETI, or some
other permutation of SETI in a decade or two.
If the galaxy is chock full of civilizations, the next question is
whether Earth is an early civilization or a late one. I can't
decide which is the better situation. If we're early and are better
than average at technological advance, then the rest of the galaxy
could have problems. We're a bit wacko, you know. Still, that might
leave us in charge--"Terra, Fuck yeah!"
On the other hand, if we're late to the game, then we may either be
subjugated (or just made irrelevant), or we may benefit by the
greater wisdom of benevolent aliens. Power rings for everyone!
Let's not spend a dime and just murder every Iranian in
Iran.
Being skeptical about claims made by the Navy or of the idea of a
missle defense system in general = Murdering every Iranian?
If a nation launched a missle that did connect, it wouldn't
necessarily mean turning that nation into a glass parking lot
(although it might). It might mean a more limited response. Or, it
might turn out that the attack was an accident or the result of a
small group of fanatical individuals. Also, if a nation did launch
a missle, I think our response to that attack should be the nearly
the same whether or not we managed to stop it before it
connected.
I personnally don't think that a missle defense system isn't worth
the cost to develop for the reasons that other posters have already
listed.
"If a nation launched a missile that did connect, it wouldn't
necessarily mean turning that nation into a glass parking lot
(although it might)."
How? It would have to or it would be open season on U.S.
cities.
"Or, it might turn out that the attack was an accident or the
result of a small group of fanatical individuals."
All the more reason to have missile defense. In a world where
missile technology is more an more avaialable to countries that
probably do not and will not same failsafe technologies the U.S.
and the USSR had and are exponentially more likely to have a rogue
general pull a Jake Ripper, the need to be able to shoot down one
or two missiles is a lot greater than it was in even the cold war.
Further, how does the U.S. know for sure that the attack was a
mistake? It is a lot easier to give a country the benifit of the
doubt for a splashed missile than it would be for a destroyed
city.
"Also, if a nation did launch a missile, I think our response to
that attack should be the nearly the same whether or not we managed
to stop it before it connected."
So you think we might not fully respond to a successful attack but
would to an unsuccessful attack? That makes no sense. If the U.S.
shoots down a missile, it has the option of not retaliating
fully.
"I personally don't think that a missile defense system isn't worth
the cost to develop for the reasons that other posters have already
listed."
Let's be conservative and think that there is a 10% chance that a
missile would ever be launched at the U.S. and a 25% chance that
the best missile defense system shoots it down. A nuclear weapon
would probably kill 100,000 Americans. That means that a missile
defense system would, assuming absurdly conservative figures, would
have a 2.5% chance of someday saving 100,000 American lives.
Considering that the U.S. government spends $1.6 trillion dollars a
year and the U.S. economy is worth $13 trillion, being unwilling to
spend even a $100 billion for such a system is madness.
Also no one in this thread has talked about the possibility of an EPC? attack. If you detonate a nuclear weapon in space over the U.S. the electronic pulse would disable some obscene percentage of the electronics in the in U.S, doing tremendous damage to our infrastructure, economy and ability to defend ourselves. Imagine if every piece of medical equipment in the country stopped functioning at one time. Imagine every car and truck in America that has a computer controlled engine (nearly every one) not starting. Imagine another 9-11 under those conditions. That is in some ways just as or scarier than a direct nuclear attack.
PL
While I think we may find better ways to communicate, we are likely
to find other uses for the Radio/MW portion of the EM spectrum.
Further, any increase in the efficiency of energy use is going to
be offset by an increased amount used, so the leakage will probably
be the same.
I think any technological civilization (can we coin 'techciv' as a
new usage here) will remain "bright" in the radio spectrum as long
as it endures.
This is all speculation, of course.
With respect to the Drake Equation, I have always felt the range of
values to be optimistic. My guess is from a high of 10-100 techcivs
presently in the Milky Way to a low of 1 arising per billion years.
[That's us, presently.]
Here's a
Drake Equation Calculator for those who wish to join into this
subthread.
I usually come up with 250 or so communicating civilizations when I
plug numbers into the equation. However, my intuitive estimate is
more like 1,000. That's pretty optimistic, but who knows? If we
continue to detect nada for the next hundred years, I may revise
that estimate. It is possible that we're among the first, which
would mean that even if technological civilizations are (or will
be) common, we're too early on the scene to find anyone else.
PL
We could be the first - Scientific American had an interesting
article a year or so back about the abundance of 'metals' ( = atoms
heavier than helium) in the Milky Way. Apparently - it was only
around the time that the sun formed that the abundance in the
"habitable zone" of the Milky Way galaxy got high enough for
carbon-based life to evolve.
{Hopefully, we're not # 2, with # 1 being Boskonia.)
Aresen,
That's an excellent point that has occurred to me as well. We know
that it took X generations of stars to generate sufficient
quantities of higher elements to make us. If we're typical, then
life like us could only have evolved since the magic moment was
reached. Of course, whether our way is the only or best way is
another question. I rather doubt there's only one way to build
intelligent life.
I wouldn't bet much on us being the earliest. We may be among the
first group in this galaxy, I suppose, but I doubt it. There's
probably some super race of helium beings out there or
something.
If we are the first, then we better get crackin' and begin
establishing the Terran Empire.
PL
I always disliked the expression "life as we know it". It is far
too limiting.
However, it is the only basis we have for extrapolation.
I really hope they turn up life in Europa's oceans or under the
surface of Mars that doesn't use adenine-guanine-cytosine-thymine
for it's encoding molecule. Then we'll have two reference
points.
The problem with an EMP bomb is that the launch is highly visible and totally unexpected. Everybody tells everybody else before they launch a satellite or orbital mission, just so nobody gets the idea that an unannounced launch is really a weapon and reacts accordingly. You would somehow have to get the weapon in orbit above the US without anybody attempting interdiction, which means it can't be delivered from anywhere but a reputable launch facility (NASA, ESA, maybe the Russians). It's possible, I suppose, to smuggle a nuclear device by launching a fake satellite, but you'd have to get past the inspectors first. I don't think the Europeans are corrupt enough to let a nuclear device past security, but the Russians might be. They certainly seem rather schizophrenic on security, simultaneously fighting a war with the Islamists on their border while protecting Iran (who supports said Islamists).
EMP. Which is why this crap is so silly, and such a welfare
scam.
And why I keep a point ignition setup for my Harley, and why I dont
want "recognition chips" in the butts of my firearms.
You pimps want endless billions of extorted funds to finance
cockamamie "weapons systems", snivel and whine about paying for
PTSD & heavy metal poisoning from DU rounds, and now Brain
Injuries!!!, and want to establish US soldiers are just pawns for
crackpot Napoleons, or loonie christcreeps.
I knew Id find y'all on Freep & chickenhawk radio sites. Damned
if I dont find you punks here, too.
Well, there you go: humanities toxic mold. Chickenhawks &
epaulette fetishists.
Glad I found a source of cheaper vodka......
Isn't one risk of developing a missle defense that we threaten the stability imposed by MAD? Without a nuclear deterant no country to stand up to us. I would hate to think someone is tapping their finger on "the button" thinking this is their last chance to avoid US domination. Of course it would be crazy to nuke us just because they won't be able to later, but if anything is going to push a government to nuke us it might be the thought that this is their last chance to "defend" themselves. (I imagine they would first demand we dismantle our still incomplete missle defense.)
Drake Equation
From
http://www.crichton-official.com/speeches/speeches_quote04.html
+++
In 1960, Drake organizes the first SETI conference, and came up
with the now-famous Drake equation:
N=N*fp ne fl fi fc fL
...
This serious-looking equation gave SETI an serious footing as a
legitimate intellectual inquiry. The problem, of course, is that
none of the terms can be known, and most cannot even be estimated.
The only way to work the equation is to fill in with guesses. And
guesses-just so we're clear-are merely expressions of prejudice.
Nor can there be "informed guesses." If you need to state how many
planets with life choose to communicate, there is simply no way to
make an informed guess. It's simply prejudice.
As a result, the Drake equation can have any value from "billions
and billions" to zero. An expression that can mean anything means
nothing. Speaking precisely, the Drake equation is literally
meaningless, and has nothing to do with science.
...
SETI is a religion.
