Bush vindicated on stem-cell issue

"If human embryonic stem cell research does not make you at least a little bit uncomfortable, you have not thought about it enough." — James A. Thomson

WASHINGTON — A decade ago, Thomson was the first to isolate human embryonic stem cells. Last week, he (and Japan's Shinya Yamanaka) announced one of the great scientific breakthroughs since the discovery of DNA: an embryo-free way to produce genetically matched stem cells.

Even a scientist who cares not a whit about the morality of embryo destruction will adopt this technique because it is so simple and powerful.

The embryonic stem-cell debate is over.

Which allows a bit of reflection on the storm that has raged ever since the August 2001 announcement of President Bush's stem-cell policy.

The verdict is clear: Rarely has a president — so vilified for a moral stance — been so thoroughly vindicated.

Why? Precisely because he took a moral stance. Precisely because, as Thomson puts it, Bush was made "a little bit uncomfortable" by the implications of embryonic experimentation. Precisely because he therefore decided that some moral line had to be drawn.

In doing so, he invited unrelenting demagoguery by an unholy trinity of Democratic politicians, research scientists and patient advocates who insisted that anyone who would put any restriction on the destruction of human embryos could be acting only for reasons of cynical politics rooted in dogmatic religiosity — a "moral ayatollah," as Sen. Tom Harkin so scornfully put it.

Bush got it right. Not because he necessarily drew the line in the right place. I have long argued that a better line might have been drawn — between using doomed and discarded fertility-clinic embryos created originally for reproduction (permitted) and using embryos created solely to be disassembled for their parts, as in research cloning (prohibited). But what Bush got right was to insist, in the face of enormous popular and scientific opposition, on drawing a line at all, on requiring that scientific imperative be balanced by moral considerations.

History will look at Bush's 2001 speech and be surprised how balanced and measured it was, how much respect it gave to the other side. Read it.

Here was a presidential policy pronouncement that so finely and fairly drew out the case for both sides that until the final few minutes of his speech, you had no idea where the policy would end up.
