The facts on DDT

Thanks to reader Jim Norton, who points to this letter to the Oz on DDT from parasitologist Dr Alan Lymbery, demolishing the nonsense peddled by Christopher Pearson (it’s on Keneth Miles site). My take on Pearson’s nonsense was here, with links to earlier pieces. I’m pleased to see it matches Lymbery almost point for point.

One fact Lymbery adds, of which I was not aware, is that Rachel Carson, who has been much maligned in the debate on this topic, explicitly noted, in relation to the growth of resistance arising from indiscriminate use of DDT

No responsible person contends that insect-borne disease should be ignored . . . The question that has now urgently presented itself is whether it is wise or responsible to attack the problem by methods that are rapidly making it worse

Lymbery concludes

Malaria is responsible for enormous suffering and death. The facts are readily available in the scientific literature. To blame a reduction in DDT usage for the death of 10-30 million people from malaria is not just simple-minded, it is demonstrably wrong. To blame a mythical, monolithic entity called the environmental lobby for the total reduction in DDT usage is not just paranoid, it is also demonstrably wrong. Your article is not only poor journalism, it is an insult to the people who work for the control of parasitic diseases that afflict developing nations.

The same could be said of the dozens of junk science sites in the blogosphere that have reproduced the same nonsense, usually with no attempt to check original sources.

Blowing up pipelines

This piece by William Safire alleges that the CIA was engaged in terrorist activity in Russia in the early 1980s, sabotaging a gas pipeline funded by Britain and Germany, and allegedly leading to its explosion.

Of course, Safire doesn’t use the word terrorism and regards the whole thing as a major victory in the Cold War, but we don’t need to use our imagination to see how the US would regard the same thing done in reverse – blowing up pipelines is one of the main terrorist activities of the Iraqi insurgents.

The sabotage was allegedly done by supplying defective computer chips of a type that were under embargo because of their supposed military use. I get the impression Safire thinks that this makes the deal OK and that it’s different from blowing up the pipeline with dynamite (but I can’t be sure of this).

Finally, I should add that the story sounds phony to me.

Unchangeable minds

Among the famous quotes attributed to JM Keynes, one that stands out is

When the facts change, I change my mind – what do you do, sir

I am reminded of this whenever I read discussions of what was in the minds of those who pushed us into the Iraq war. It’s regularly stated that the behavior of Saddam Hussein in obstructing weapons inspections led analysts to assume he had something to hide. I shared this view until late 2002, and was reinforced in this by the behavior of Bush and Blair, including the various dossiers they published and the push for UN Resolution 1441 – they acted like police who had their suspect dead to rights, and only needed a search warrant.

In November and December 2002, however, the facts changed. First Saddam announced that he would readmit UN inspectors, without restrictions on the sites to be inspected and that he would declare all his weapons. Then he proceeded to do just that, claiming to have no weapons at all. Meanwhile Bush and Blair suddenly started hedging about the nature of the knowledge they had declared. The same pattern proceeded right up to the outbreak of war. Time after time, some condition would be declared crucial by Bush and Blair (overflights, interviews with Iraqi scientists, out-of-country interviews with Iraqi scientists), the Iraqi government would agree after a brief delay and then new condition would be raised. As quite a few observers noted, the behavior was the same as that of the Austro-Hungarian government with respect to Serbia in 1914.

Given the change in facts, any unbiased observer would have concluded, correctly that the balance of probabilities favored the hypotheses Bush and Blair were bluffing and that there were no weapons of mass destruction in usable form. I drew precisely this conclusion at the time, though with the mistaken corollary that Blair would stick to his word and refuse to go to war once Saddam called their bluff.

If those facts weren’t enough, it was obvious that, if Saddam did have weapons he would use them in the early days of war, preferably before Coalition troops had entered the country. Thus, it was apparent by the first days of the war that (with probability close to 1), there were no usable weapons. The fact that the contrary belief prevailed for so long is testament to the power of faith in the face of experience.

What I'm reading, and more

I’m still working through the O’Brien/O’Brian (Patrick and Flann) section of the bookshelf. I missed the movie of Master and Commander, as I was out of town too long, and will have to watch it on DVD, which will definitely be a second-best option for this kind of film. I did see Japanese Story, a film with a rather slight plot, but an excellent performance from Toni Collette.
