National Security Policy, Nontraditional Threats, and Other Things

It's always interesting attending a Stammtisch gathering at the home of Les Johnson. There is no lack of interesting discussion material or vocal opinions. Tonight's edition featured a guest speaker, Dr. Kathy Hawk, who discussed "National Security Policy and Nontraditional Threats." Dr. Hawk has an interesting background, covering experiences as varied as the U.S. Navy, the Strategic Defense Initiative Office (SDIO), the U.S. Foreign Service, and teaching at UAHuntsville.

Any discussion of contemporary U.S. policy has to start with World War II and the Cold War, both of which presented relatively straightforward national security concerns. The Cold War, especially, provided a relatively easy problem for our national security apparatus: protect ourselves from communism overseas and at home by keeping ourselves strong on both fronts. With the collapse of the Soviet Union, the U.S. experienced several new challenges:
  • Many more independent state players appeared on the scene (as opposed to facing a "bipolar" world)
  • Advanced or dangerous technologies became more available to more people
  • Unstable or failed states became homes to criminal and terrorist actors with no nation having a clear mandate (or will) to do anything about them
  • Individual criminals or terrorists were increasingly pursuing agendas hostile to American interests, with or without the support of a nation-state
The most dramatic example of this multipolar world is perhaps the 9/11 attacks, which set the paradigm for national security in the 21st century. Internationally, the U.S. and other Western nations launched a "War on Terrorism" while domestically they centralized their domestic security apparatuses through agencies such as the Department of Homeland Security (DHS). The mandates for Western nation-states didn't change--keep the nation safe from threats foreign and domestic--the challenge has become identifying the best way(s) to do that. DHS was built to bring down the "walls" between various intelligence agencies that allowed Osama bin Laden to slip through the cracks and his followers to seize control of four airplanes one day in September. Unfortunately, in reacting to similar types of threats, DHS has come to impinge on freedoms here at home.

Which begs the question: if you keep the people "safe" from terrorists but regulate and police them relentlessly, is that way of life really worth protecting? Needless to say, with a group of opinionated adults in the room, there were plenty of sidebars and other topics brought up in response to that line of discussion. My comment along these lines was that as national security threats have moved from state actors (Communist Russia) to individuals, governments have tended to target their protective measures down to the size of the actor involved. If the threat is from another country, you set up an army; if the threat is from individuals, you try to regulate individuals. That isn't the best way to ensure freedom, necessarily, but it is a natural consequence of how most governments operate.

Another important topic Dr. Hawk covered was what we mean by power. I was curious to see that her definition of power matched my own: the ability to make someone else do something they would not do otherwise.

In addition to terrorism and international criminal activities (anything from narcoterrorism to slaving), the world community faces potential threats from cyber attacks, unconventional weapons (e.g., nukes), environmental issues (global warming/cooling/climate change), and infectious diseases. If the U.S. is going to obtain cooperation from other nations on how to handle these issues, it will need a combination of hard (military) power and soft (diplomatic) power. These issues are complicated enough when negotiating with national governments that have some control over what things are done by their citizens or on their behalves; it gets much more complicated when national or local governments have little to no control over their populations or if those governments are compromised by criminal elements or corruption. It's one thing for Chinese People's Liberation Army launches a cyber-attack against U.S. information networks, it is something else when individuals like Osama bin Laden or Julian Assange pursue their own agendas without any clear support from anyone.

Another sidebar topic (I somehow doubt it was in Dr. Hawk's prepared remarks) was on the general decline in American power in the last X years--pick your timeline--and the potential sources of that decline. Explanations ranged anywhere from cultural rot to slacking youths to military decline to a general failure of national will to our own success. This last argument was forwarded by Les, who suggested that the rest of the world saw what hard work, capitalism, and technology could do, and decided to imitate our success. Having built our nation up to a certain level, we want to relax and enjoy ourselves while other nations are hustling to catch up to us. The world might be less admiring of the values that we claim to hold most dearly: freedom of speech and action, for example, since Hollywood regularly puts out movies and TV shows that depict a nation of people using or abusing their freedom badly--not the best "advertisement" for the American way of life.

The topic of global warming brought up all sorts of side chatter, ranging from the veracity of the climate models to the real efficacy of "going green" when China and India are building the equivalent of a coal plant a day. Say the U.S. was able to completely electrify its economy and switch to other power sources, but the world's two most populous nations continue to burn fossil fuels. What have we done to help the world in that case, and what could we do from a political power perspective to get those nations to "go green?"

One theme Dr. Hawk returned to as we wound down the evening was the danger of failing or failed states, which become a magnet for bad actors. Corruption, crime, and instability in such places (Afghanistan, Somalia, Zimbabwe) make those nations much less able to respond to issues that require coordinated international effort, such as climate, disease, or space-related threats (I brought up asteroids as a case in point). Someone asked, "So you're suggesting we take on international crime as a way to combat global warming?" It sounds convoluted or counter-intuitive, perhaps, but it made sense to me. In a nation with stable political, social, and physical infrastructure, it is more likely for the citizens of that country to feel safe enough to become politically engaged and make positive contributions to their nation and the world at large.

But lots of questions remain: is it the duty of the U.S. or some other great power to police or stabilize the Somalias of the world? Do we merely contain those areas or use hard/soft power to bring things under control? This being a Stammtisch of engaged citizens, not the U.N., we didn't have any immediate answers or solutions, but as always, a really good conversation.

Book Review: Going Interstellar

It's a tough market for trying to "sell space" right now. Budgets are tight for space agencies worldwide, and there's no telling how long it will take for some of our more ambitious missions to the moon, Mars, or an asteroid to come to pass. So it might seem a little outlandish to be talking about missions out of the solar system--to other stars, no less!--but that is the exact point of Going Interstellar, a new anthology of articles and short stories about interstellar travel using current technologies.



The editors (Les Johnson and Jack McDevitt) and writers of this book have decided to throw caution to the wind, daring to talk about how human missions beyond our solar system might unfold. The technical articles in the book are brisk and light on equations or technobabble. In addition to Johnson, who's written extensively about solar sails and other high-tech propulsion systems, Dr. Greg Matloff has added articles on fusion and antimatter starships. They make it clear that the systems needed to span the incredible distances between stars are all technologically feasible, and none of them require "warp drive" or violations of known physics. Of course it should be pointed out that "feasible" is a long way from "doable right now." For instance, the ability to generate every Star Trek fan's favorite, antimatter, would take years. The energy output would be akin to half the world's total current production and would require special facilities out near Mercury's orbit. Hydrogen fusion, another favorite of science fiction writers, is also elusive, but we're at least working on it. "The rest," as physicists might say, "is just engineering."

The stories in this book are quite engaging. In fact, I finished this book over the course of three days. With stories by Ben Bova, Jack McDevitt, Louise Marley, Michael Bishop, Sarah A. Hoyt, and Mike Resnick, Going Interstellar looks at adventures beyond the solar system from a variety of unique perspectives, including an aging astrophysicist, a technologist in an interstellar feudal society, an artificial intelligence program, a teenager, and the next Dalai Lama. Interstellar travel is a bit like other frontiers for writers where there is little known about the place or the experience of getting there. It allows them to impose their own dreams and obsessions on a blank slate, much like Sir Thomas More place his Utopia in America. Intelligent machines? A reborn Tibetan culture? Why not?

What I liked about this book, beyond the brisk pace of the writing by multiple authors, was its willingness to touch on something that sometimes is sorely lacking: technological optimism without "magic." As I noted above, there is no faster-than-light-speed travel, no instantaneous travel between stars. This is a look at what really ambitious human spaceflight could look like using tools and machines accessible to us today, and the stories are informed by emotion, imagination, and technical know-how. In short, it's everything you'd like hard science fiction to be, and it's a pleasure to read.

Potpourri CVI

I have been accused of neglecting this blog of late, to which I can only plead guilty. I have been rearranging my priorities--partially to make room for someone else in my life besides me and my oversized glass writer's ego and partially because I've experienced a corresponding lack of interest in the hot issues of the day. Those who make talk radio or other political hot topics the center of your day should probably take note...there is a life outside of politics, and it is very good.

From Father Dan, a link to something called the Social Security Death Index, which lists (as near as I can tell) the deaths of all U.S. persons since 1962.

From the Sapporo beer label, a specialty item: beer made from space barley (i.e., barley that has been in space).

Interested in learning how to learn your fancy new Apple hardware? Check out this site. Apple provides seminars, which you can search by zip code.

My favorite rocket scientist, Les Johnson, has a new book coming out soon called Paradise Regained: The Regreening of Planet Earth. It looks intriguing--using space resources as a way to reduce the strain on Earth's environment by accessing space resources. If it is like Les's other books, it will be highly informed and clearly explained for even the English majors in the reading audience. Looking forward to reading it!

From Lin:
  • An article from the U.S. Geological Survey on a potential 3 to 4.3 billion barrels of recoverable oil lurking beneath North Dakota and Montana...one wonders if the folks advocating for energy independence in the Obama administration are listening/reading.
  • An article from Commentary Magazine, which I have but haven't read yet, on why Obama is wrong in his approach to missile defense.
  • Lin had a question about this article regarding the release of environment/climate data from NASA and one person's effort to extract it from the agency. It sounds like a Freedom of Information Act (FOIA) request got ignored, and the complainant is using the occasion of the climate data fracas at the Intergovernmental Panel on Climate Change to press his case.
On another personal note, I have been worn down by the sheer complexity of 21st century reality, and will soon be purchasing a smart phone of some kind. The folks responding to my request for inputs on Facebook have mostly recommended the iPhone, which I've rejected out of a knee-jerk anti-Apple attitude more than anything else. However, if it does what I want, I might relent. That doesn't mean I'll go out and buy a Mac next (as Father Dan might say, "Get a grip!"). Another hot item on the market right now is the Droid, which is Motorola's answer to the iPhone and features a hard-key popout keyboard that I lilke, being less than savvy with touch screens. Most of my friends and family members who have these toys use something out of the BlackBerry. What interests me is that they all use different models, and all seem equally happy with them, so I guess I might end up taking one friend's advice and just going with what looks cool. :-)

How do you keep a space geek in suspense? Tell you you'll get back to him after the next NASA program study. The Obama administration wants to emphasize international cooperation. Great. Can they at least allow Constellation/Ares/Orion to continue building hardware in the meantime?

This was a pretty good interview on NPR regarding current goings-on in space.

From Martin...an opportunity to market your own blog via t-shirt/sweatshirt. Might have to look into that. Not that I don't love the 15 of you who check in on a daily basis, but eventually I might need to pay bills with this site, ya know?

A Business Week article on the Singularity University giving lectures to CEOs about the future. Sounds cool. Anyone got 25 grand they care to loan me?

From Gwen: An Arizona public school teacher lost his job for running the SETI @ Home application from his work computer.

From D2:
  • On a slow day, I was wondering aloud what I could do to make myself more useful or marketable in my current line of work. Dede suggested looking at the IRS tax credit available under the American Recovery and Reinvestment Act (ARRA, a.k.a., the stimulus) for lifetime learning expenses. I'm far from a pure libertarian on such things--I got through my M.A. with a federal loan--but a) I'm not sure how long ARRA money will be available, and b) I can probably find better ways to spend my time and other people's money.
  • Xerox is offering the opportunity to send "thanks to the troops" postcards. Worth checking out.

A good editorial by Patti Grace Smith (former FAA person in charge of Commercial Space Transportation and now an aerospace consultant on why commercial rockets to the International Space Station are not inherently unsafer than government-built vehicles. I go around and around with my coworkers on this issue. The usually concede that commercial entities could do the job, but they haven't done it yet; ergo government must continue to do it. Yeah, I contend, but for how long? At which point the conversation peters out, as I hear vague terms like "human rating" and "flight rate." The federal budget is not endless, and NASA will not get much past the Moon until it is set free from low-Earth orbit and ISS operations. Just sayin'.

That's about it for now. Be good to yourselves and each other. There's a lot of weirdos out there.

Potpourri CXIII

Today's little doses of the different:

The U.S. Science & Engineering Festival, the first national science festival, will be happening in Washington, DC, October 23-24, 2010.

From Dar, Data in the Cloud from Dallas to Mars. This article on the blog Shepherd's Pi talks about Microsoft's latest search engine system, which appears to be a sort of hyper-Google, designed both to compete with Google and to do things they can't do, like assign meanings or draw trends from very large sets of data.

From Yohon, a link to a new science/space publisher.

From ABC News, of all places, a report that jobs the Obama administration claims to have saved or created exist in congressional districts that don't even exist. I'm shocked, shocked...

From Doc:
Want to be a Martian? NASA has a web site for that.

From NASAWatch (really?): Help choose the best public service announcement in support of NASA.

If you're interested in the works of an honest-to-gosh Rocket Scientist, check out the web site of Les Johnson, a very smart fellow whom I've had the pleasure of chatting with, reading books by, and participating on a panel at a sci-fi convention with. Les is an excellent writer because he is also an excellent and patient teacher--he takes the time to explain very difficult things in words that illuminate without insulting the reader. These are all good skills to have.

From AIAA:
  • Richard Branson, founder and owner of the Virgin family of companies, wants Virgin Galactic to eventually fly tourists around the Moon. Great, if he can do it and I could afford it.
  • A UCF professor was profiled in the Chronicle of Higher Education for his efforts to promote zero-gravity experiments on privately built suborbital rockets.

And that'll about do it for now.

Solar Sail Alternative

Marshall Space Flight Center scientist Les Johnson has been pushing for the U.S. to develop very large solar sails as a means of propelling long-distance exploration missions. However, this article suggests going the other way: small sail, very small payload. Fascinating, Captain.
