Missile shield to be scrapped

It's a great day. This piece of news makes me feel extremely gratified as I am sure it does many others. Missile defense against ICBMs has been an eternal bug that has bitten almost every President since 1960. The Bush administration had aggressively pushed plans to implement a missile shield in Poland and the Czech Republic. There has always been evidence that the efficacy of such a shield will ultimately be severely limited by the basic laws of physics, and that the adversary can essentially and cheaply overwhelm the defense with decoys and countermeasures.

I have written about these limitations and studies about them several times before (see below). The best article arguing against the European missile shield is a May 2008 article by Theodore Postol and George Lewis in the Bulletin of the Atomic Scientists (free PDF here).

And as arms expert Pavel Podvig succinctly wrote in the Bulletin of the Atomic Scientists only three days back, it's not just about the technology, but it's about a fundamentally flawed concept:
"The fundamental problem with the argument is that missile defense will never live up to its expectations. Let me say that again: Missile defense will never make a shred of difference when it comes to its primary mission--protecting a country from the threat of a nuclear missile attack. That isn't to say that advanced sensors and interceptors someday won't be able to deal with sophisticated missiles and decoys. They probably will. But again, this won't overcome the fundamental challenge of keeping a nation safe against a nuclear threat, because it would take only a small probability of success to make such a threat credible while missile defense would need to offer absolute certainty of protection to truly be effective...It's understandable that people often talk about European missile defense as one of the ways in which to deal with the missile threat posed by Iran. Or that someday missile defense could provide insurance for nuclear disarmament--this is the vision that Ronald Reagan had. When framed in this way, missile defense seems like a promising way out of difficult situations. But this promise is false. If a real confrontation ever comes about (and let's hope it never happens), we quickly would find out that missile defense offers no meaningful protection whatsoever".
Now the Obama administration has decided to scrap the unworkable shield and has decided to replace it with a much more realistic defense against short-range missiles. I cannot imagine how gratified this must make the scores of scientists, engineers and policy officials who have long argued against the feasibility of the shield. It also signals a huge shift in Bush-era foreign policy. Notice how the administration has diplomatically and shrewdly avoided mentioning the basic failures of the earlier system.

Unfortunately, the sordid history of missile defense and the inherent satisfaction that seems to stem by arguing in favor of a "shield" to protect the population makes me skeptical in believing that the concept is dead forever. But for now, there is peace in our time and this is a significant breakthrough.

History

Till I was about 13 or 14 years old, my readings of American history consisted only of offerings from the history of the United States during World War 2, an old and enduring historical interest of mine. It was when I picked up Harold Evans's The American Century, a superb and magisterial illustrated history of the country during the twentieth century, that I became painfully and woefully aware of the injustice that African-Americans faced in this country for two hundred years. I was horrified to read about Jim Crow, the dog squads and water hoses on the streets of Montgomery, Alabama, the lynchings in Mississippi. As a boy who was about the same age then, I was especially sickened and completely shaken by the relatively recent story of Emmet Till, a story that has been vividly seared into my mind ever since.

I could not believe that this was the country enshrined in the Declaration of Independence, the land which first and foremost looked at the integrity of one's character and his or her abilities and not where he or she came from. And yet I saw hope and fundamental human decency in Martin Luther King and the Civil Rights movement. But since then, I have often felt whether any event or moment in the United States could possibly mentally transport me to a pre-Harold Evans time when I had a singularly auspicious and pristine perception of this country. Such a moment would never come because one cannot erase the scars inflicted on this country's character for two hundred years. But I feel convinced that if there would be a moment closest to such a moment in my life, that moment would be yesterday night.

At midnight, I stood on the 15th floor of the Hyatt Regency Hotel and amid the car horns constantly blaring on the street downstairs, I strained my ears to catch every word that he spoke on the TV screen. The overriding feeling among everyone around me was one of peace and relief and tears even more than elation.

He looked tired, relieved and happy but not jubilant. He knows the difficult task that lies ahead and knows that celebration right now is premature. He knows that there's much to be done and that this is just the beginning. He knows that he may not be able to bring about a sea change in the way things have been done. But he knows that he will nudge the country in the right direction by valuing and fostering rationality and honest debate. He knows he will be upfront and forthright about what he thinks and he understands the value of the journey, even if the final destination may not be known. He understands the value of incremental progress.

And he knows that his extraordinary story culminating in yesterday's night healed at least some of the internal divisions among his own people and will go a long way in reviving his country's image in the world as the land of opportunity, diversity and respect.

He did it. Now we have to do it. Now we can get back to our lives.

Save Science on Tuesday

It was Richard Nixon who got rid of the Presidential Science Advisory Committee during his tenure, which has not been resurrected since. In the 80s, Ronald Reagan embraced the idealistic vision of Star Wars, a pipe dream that did not have a valid scientific basis. In the 90s, Congress got rid of the Office of Technology Assessment which is supposed to provide the country's political leaders with bipartisan scientific advice. Science on the whole in the last twenty five years has been on a downhill path as far as respect for it in political circles has been concerned.

Although George Bush's administration has been the single-largest malefactor of science and all it stands for and in general although Republicans have done more damage to science, all administrations since the 1970s have overall been lax and negligent in supporting science and its essential spirit. As I have written before, the issue goes far beyond the important one of providing funding for basic scientific research. It has to do with trusting unbiased advice that tries to give you a picture of the world as it is, and not how you would like to see it. It has to do with promoting and respecting open-mindedness and true bipartisan debate. Thus science has always stood opposite dogma, a fact that is usually hard to swallow for most politicians who would want to color the world with their own ideological brush. This is a wholly fatalistic attitude because a disrespect for science means an abandonment of informed decision making, eventually a sure path for a country's spiral into regress.

Barack Obama is not good for science because he is a liberal Democrat. He is good for science because he largely stands for all that science traditionally has; open minds, patient and careful thought, forthcomingness and respect in listening to dissenting opinions, a mistrust of blind reliance on authority and a willingness to listen to all sides of the debate before taking an informed decision. Obama also knows he is not perfect and embodies another key aspect of science; the ability to understand one's deficiencies and limitations and seek the best possible advice to overcome them. There is scarce doubt that he will bring knowledgeable science advisors into the White House and that he will take seriously the advice of people with whom he may not agree. At the same time he will weigh all the options and sides and try to take as unbiased a decision as he can. In an age of climate change, evolution, food crises, energy crises, drug resistance and nuclear terrorism, science is going to become an increasingly key and vocal part of the national debate and the future of this country. Obama understands this. Maybe that's why, a few days ago, 76 Nobel Prize winners represented by the great physicist Murray Gell-Mann wrote an open letter to the American people and endorsed Obama as most prudent for science in this country.



The American people need to reclaim their lost preeminence in science and technology and their respect for learning and rationality. They need to reaffirm their place in the world as the land where open minds meet unlimited resources and intellectual capital. The time has come when this land needs to save science from itself. With this in view, anyone who deeply cares about science, reason and objective thought should vote for Barack Obama on Tuesday.

Please, don't stand in the way of this man

This is as sensible and assertive a statement about evolution that we can expect from a Presidential candidate
Do you believe that evolution by means of natural selection is a sufficient explanation for the variety and complexity of life on Earth? Should intelligent design, or some derivative thereof, be taught in science class in public schools?

Obama: I believe in evolution, and I support the strong consensus of the scientific community that evolution is scientifically validated. I do not believe it is helpful to our students to cloud discussions of science with non-scientific theories like intelligent design that are not subject to experimental scrutiny.
This is from the latest issue of Nature whose cover story is about the candidates' views on scientific issues, views that are going to be of paramount importance to the future well-being of this country. Nature asked the candidates 18 questions about science and technology, including questions about increasing funding for basic research, speeding up the track to permanent residency for talented foreign students, and pumping more funds into biomedical innovations.

Not suprisingly, McCain's camp declined to answer with specifics and Nature dug up relevant statements from his old speeches that mainly included boilerplate sound-bytes. Obama's camp on the other hand provided rather eloquent and clear answers that actually talk about facts. It's pretty amazing to hear answers that actually are filled with details about science. McCain's cast of "science" advisors looks like a Gilligan's Island outfit and includes HP chief Carly Fiorina (who thinks Sarah Palin is quite competent to be President), James Woolsey, a former CIA director and Meg Whitman, former CEO of EBay. This group seems as miscast for science as Sarah Palin is miscast for being Vice President. Obama's advisors on the other hand include some real scientists, including Dan Kammen from Berkeley and Harold Varmus from Sloan Kettering Cancer Center.

Obama would speed up the residency process for foreign students and minimize barriers between private and public R & D (this is going to be very important). And Obama is as clear about nuclear energy as anything else
What role does nuclear power have in your vision for the US energy supply, and how would you address the problem of nuclear waste?

Obama: Nuclear power represents an important part of our current energy mix. Nuclear also represents 70% of our non-carbon generated electricity. It is unlikely that we can meet our aggressive climate goals if we eliminate nuclear power as an option. However, before an expansion of nuclear power is considered, key issues must be addressed, including security of nuclear fuel and waste, waste storage and proliferation. The nuclear waste disposal efforts at Yucca Mountain [in Nevada] have been an expensive failure and should be abandoned. I will work with the industry and governors to develop a way to store nuclear waste safely while we pursue long-term solutions.
Most importantly, Obama promises to reform the political environment for scientific opinion; this would include appointing a Chief Technology Officer for the government and strengthening the President's Scientific Advisory Committee, a key source of scientific advice for the President that was abolished by the odious Richard Nixon
Many scientists are bitter about what they see as years of political interference in scientific decisions at federal agencies. What would you do to help restore impartial scientific advice in government?

Obama: Scientific and technological information is of growing importance to a range of issues. I believe such information must be expert and uncoloured by ideology. I will restore the basic principle that government decisions should be based on the best-available, scientifically valid evidence and not on the ideological predispositions of agency officials or political appointees. More broadly, I am committed to creating a transparent and connected democracy, using cutting edge technologies to provide a new level of transparency, accountability and participation for America’s citizens. Policies must be determined using a process that builds on the long tradition of open debate that has characterized progress in science, including review by individuals who might bring new information or contrasting views. I have already established an impressive team of science advisers, including several Nobel laureates, who are helping me to shape a robust science agenda for my
administration.
This point is the most encouraging policy vision, after a 8 year tradition of bullying, manipulating, cherry picking, ignoring and roughing up science and objective facts. The cost of scientific ignorance will be progress in all its forms.

Reading this is like being immersed inside a gutter for 8 years and suddenly coming up for fresh air in the bright sunlight with a gasp. We finally see a political leader who can actually think and give serious thought to all sides of a problem including dissenting ones. There's a scientist in Obama somewhere. This man deserves to lead this country. This country (at least for those who care) deserves to be led by this man.
