MIT Technology Review interviews rocket scientist Franklin Chang Diaz
This coming January, Ad Astra Rocket Company will test the VX-200, a full-scale ground prototype of the variable specific impulse magnetoplasma rocket (VASIMIR), first conceived in 1979 by the company’s president and CEO, astronaut and plasma physicist Franklin Chang Diaz. The rocket is an attempt to improve on current space-propulsion technologies, and it would use hot plasma, heated by radio waves and controlled by a magnetic field, for propulsion. Chang Diaz believes that the system would allow rockets to travel through space at higher speeds, with greater fuel efficiency.
If the prototype demonstrates sufficient efficiency, thrust, and specific impulse on the ground, the next step will be the VF-200, a flight version of the rocket. Ad Astra plans to fly the VF-200 to the International Space Station, where it would help maintain the space station’s orbit. If all this goes according to plan, Chang Diaz hopes to eventually build VASIMIRs that could travel to Mars and beyond. In advance of his appearance at the Emerging Technologies Conference this week, Technology Review talked with him about the near future of space exploration…

…”Presidential Sweepstakes” — a curious term, as I reflect upon it, but surprisingly accurate.
Contrary to the myth that the elected Chief of the executive branch of the national government in the United States is a public servant, this official — “the President” — is much more like the winner of a sweepstakes. The odds at the beginning of each election cycle for anyone but a first-term incumbent President to win election to that exalted office are small. But the pay-off from winning the sweepstakes is huge — lots of prestige; a nice, fully staffed house; a nice big airplane; bodyguards for life; enormous demand for your services (such as they might be) when you are no longer in office; your name in the history books; rock-star-like fame; and torrents of influence and power.
Does anyone in the world really think that being President of the United States is a sacrifice, sort of like being President of the East Alabama Old Car Club?
I doubt it. U.S. presidential elections are the world’s grandest sweepstakes, with one enormously lucky winner every four years. And just as each person who enters the Publishers’ Clearinghouse Sweepstakes does so because he or she hopes to win incredible personal benefits, so, too, with Presidential candidates: they’re in it overwhelmingly for themselves, not for the welfare of the rest of us.

Via Glenn, Megan McArdle offers thoughts on the American public’s preference for lower taxes at the Atlantic Monthly:
Returning a bit to the topic of supply-side economics, there seems to be a general feeling among my progressive/liberal friends that the main reason America has such a hard time raising taxes to cover the new spending programs they want is that Republicans have been ceaselessly demonizing taxes for the last thirty years, while spreading vicious lies about supply-side economics that have instilled a new and pernicious tax hatred among American voters. This is basically the narrative of The Big Con: we used to have this terrific economy with low inequality and a growing government share of national income, with everyone except a few rich malcontents happy, then this giant Republican conspiracy to make us all hate taxes came along and lured us off the Yellow Brick Road and onto the Road to Perdition.
This seems an odd belief to hold in a nation that was basically founded in a tax revolt. A modestly comprehensive perusal of pre-1970 literature reveals that Americans seem to have hated taxes all along. And why wouldn’t they? Taxes don’t need any special conspiracy to make you hate them, at least if you are among the majority of people who would rather have more money in your pocket than less.
I think a better explanation for the shift in public sentiment about government spending that took place in the 1970’s would point out two things: first, that the government in the late 1960’s and early 1970’s was doing a really spectacularly bad job of running the economy. Richard Nixon was probably the worst economic disaster as president since Andrew Jackson, and Lyndon Johnson and Gerald Ford weren’t any particular prizes either. The economic history of the 1970’s sowed very well justified fears about state intervention in the economy, and it’s probably no coincidence that we’re getting more support for government programs only as the memories of 40 years ago begin to fade.

Quite a revealing interview by Robert Pollock in today’s WSJ. I hope Pollock is correct that “Maliki has been highly underrated”:
What about Iraq’s neighbors? Are they helpful?
“No, actually,” he admits. “At the beginning it wasn’t an issue of getting more support but suffering from their negative interventions and their breaking of the principles of good neighbors.” But he says things have started to change for the better because the surrounding countries now worry that troubles in Iraq could spread. They have “started a dialogue” with us, he says, adding “it is the duty of the entire world to work with Iraq.”
Throughout the course of our discussion I emphasize that he should regard this as an opportunity to speak his mind, not a “gotcha” game. He tells me that the overriding message he aims to deliver in New York this week is that the world must form a “united front that supports democracy and confronts terror. There is no country that can say that terrorism has nothing to do with me.”
And he thanks The Wall Street Journal for what he calls balanced coverage of Iraq–”we don’t want news organizations to do propaganda for us.”
Flattery aside, I come away with the reinforced impression that Prime Minister Maliki has been highly underrated. Sure, it might be nice to have an Iraqi prime minister with a ready smile, flawless English and the unquestioned loyalty of all the country’s people. But given the fractured nature of the country we found, and our many missteps–particularly the “proportional representation” electoral system, which encouraged sectarian politics–we should be thanking our lucky stars we ended up with Mr. Maliki. He is decent, thoughtful and courageous. He deserves our support, and patience.
“In the 1860s, your country fought a great struggle of its own”–Mr. Maliki reminded the world in an article for The Wall Street Journal in June (yes, he really did draft it himself)–”a civil war that took hundreds of thousands of lives but ended in the triumph of freedom and the birth of a great power.”

It may not have been obvious in 2003 but is completely obvious today. In brief:
• you cannot eliminate terrorists you can’t find
• you can’t find them unless the locals are willing to tell you where the terrorists are [and their bomb-making factories, etc.]
• the locals won’t tell you if the locals know the terrorists will kill them for cooperating
• therefore, you can’t find the terrorists unless the locals know you will protect them
Think about that the next time you hear soundbites from Clinton, Obama, Edwards, Reid, or Pelosi. Fred Kagan explains in more detail why the Petraeus strategy is working; why the “Clinton plan” is guaranteed to fail.
…The Sunni Arabs in Iraq lost their enthusiasm for al Qaeda very quickly after their initial embrace of the movement. By 2005, currents of resistance had begun to flow in Anbar, expanding in 2006. Al Qaeda responded to this rising resistance with unspeakable brutality–beheading young children, executing Sunni leaders and preventing their bodies from being buried within the time required by Muslim law, torturing resisters by gouging out their eyes, electrocuting them, crushing their heads in vices, and so on. This brutality naturally inflamed the desire to resist in the Sunni Arab community–but actual resistance in 2006 remained fitful and ineffective. There was no power in Anbar or anywhere that could protect the resisters against al Qaeda retribution, and so al Qaeda continued to maintain its position by force among a population that had initially welcomed it willingly.
The proof? In all of 2006, there were only 1,000 volunteers to join the Iraqi Security Forces in Anbar, despite rising resentment against al Qaeda. Voluntarism was kept down by al Qaeda attacks against ISF recruiting stations and targeted attacks on the families of volunteers. Although tribal leaders had begun to turn against the terrorists, American forces remained under siege in the provincial capital of Ramadi–they ultimately had to level all of the buildings around their headquarters to secure it from constant attack. An initial clearing operation conducted by Col. Sean MacFarland established forward positions in Ramadi with tremendous difficulty and at great cost, but the city was not cleared; attacks on American forces remained extremely high; and the terrorist safe-havens in the province were largely intact.
More: Kagan discusses these concepts in the Heritage Foundation podcast from the September 13 seminar “Reporting on the Report: Assessing Progress in Iraq“.
More: Charlie Quidnunc reviews Hillary Clinton’s talk show marathon and contrasts with a clip from Fred Kagan’s talk at Heritage in this podcast “Mission Descisions – Why don’t we just fight the Terrorists in Iraq?”. Notice how Clinton keeps repeating the contrary-to-fact that the Bush strategy is purely military. I would like to see an objective poll to assess how many voters really believe such rubbish.
For some in-depth analysis that is both informed and non-partisan, see Dave Kilcullen’s Anatomy of a Tribal Revolt. “Purely military strategy” indeed! See also Kilcullen’s “Understanding Current Operations in Iraq” in Small Wars Journal [and associated commentary here]
The only way to explain why Democratic campaigners don’t “get it” is naked partisanship [translation: the desire for power].
UPDATE: Max Boot is succinct on this
Readers of contentions interested in learning more about current military operations in Iraq than what they get from the headlines (which invariably focus on casualties, not on why or how they were incurred) would be well advised to read two Internet postings. The first is a report by Kimberly Kagan, an independent military historian and analyst, on the website of her think tank, the Institute for the Study of War. The second is a blog post written by David Kilcullen, a former officer in the Australian army with a Ph.D. in anthropology who has been serving as General David Petraeus’s chief counterinsurgency adviser. Kilcullen’s item is especially interesting because for the past few months he has had an insider’s perspective on the operations conducted and planned by U.S. forces in Iraq; in fact, he has been helping to shape the very operations that he explains here.
I have little to add except to note the cognitive dissonance I feel reading Kilcullen’s report alongside the news media accounts. The former conveys a sense of purpose and planning behind current operations, while the latter present the news from Iraq as a senseless parade of mayhem. The reality, of course, lies somewhere in between—there is only so much that even the most astute military commanders can control in the heat of battle, and much of what happens is outside their design. But it is important to realize that what we’re seeing in Iraq is not just random, meaningless violence. Both sides—coalition and Iraqi forces, as well as the Sunni and Shiite extremists—put a lot of thought into what they do. This is a war, even if a very decentralized one, and needs to be understood as such. Kilcullen’s post furthers that crucial understanding.
Robert Kaplan explains the real story in the latest Atlantic Monthly:
…Mention private military contractors to many civilians, especially to liberals, and they’ll think of red-state good old boys working for a firm like Halliburton—the Texas-based corporation formerly run by Vice President Dick Cheney—who appear to constitute a rogue, mercenary element favored by a Republican administration.
In fact, the former Halliburton subsidiary of Kellogg, Brown and Root (KBR) consummated its veritable marriage with the U.S. military during the Clinton administration, when the firm’s logistical capabilities were indispensable to the Balkan interventions that many liberals supported. The KBR-designed military bases in Bosnia and Kosovo became templates for those in Iraq and Afghanistan.
Rather than mercenaries who will fight for the highest bidder, private contractors like KBR and Blackwater are composed mainly of retired American noncommissioned officers (NCOs), working alongside the same military to which they used to belong. Just as other professions tap the wisdom and expertise of retirees, so does the American military. Indeed, some contractors, like Triple Canopy, are known to hire veterans of the most elite Special Operations units in the U.S. military. “I’m hiring the elder statesmen of the combat arms community,†one Army colonel told me, referring to some private contractors he was taking on to supplant his uniformed troops in a noncombat capacity. “They won’t have to go through any sniff test when they arrive in the field as consultants. They’ll be instantly looked up to.â€
Tigerhawk found this segment in Richard Clarke’s Against All Enemies:
Snatches, or more properly “extraordinary renditions,” were operations to apprehend terrorists abroad, usually without the knowledge of and almost always without public acknowledgement of the host government…. The first time I proposed a snatch, in 1993, the White House Counsel, Lloyd Cutler, demanded a meeting with the President to explain how it violated international law. Clinton had seemed to be siding with Cutler until Al Gore belatedly joined the meeting, having just flown overnight from South Africa. Clinton recapped the arguments on both sides for Gore: Lloyd says this. Dick says that. Gore laughed and said, “That’s a no-brainer. Of course it’s a violation of international law, that’s why it’s a covert action. The guy is a terrorist. Go grab his ass.” (pp. 143-144)
This passage is especially interesting in light of Gore’s more recent speechifying, in which he specifically denounced rendition. No more “go grab his ass.”
Al Gore supported rendition before al Qaeda had declared war on the United States and hung its battle flag on the Khobar Towers, the USS Cole, the African embassies, the World Trade Center, the Pentagon, the Bali disco, the Madrid trains, and the United Nations. But after those defeats, Al Gore changed his mind. Has any reporter for any major news organization bothered to ask Gore to explain his reasoning?
With medical costs skyrocketing, the middle class struggling, and heartless Republicans running the government, what has happened to the percentage of children without health insurance over the past seven years?
