Popular Mechanics has an interesting article on the technology of missile defense. It takes a somewhat skeptical tone, which I suppose is fair, but what isn’t fair is their misrepresentation of the testing record:
Which leaves a vital question: Does the system work? That’s a matter of fierce debate, and the success rate of tests is mixed. Since 1999, the MDA’s strategic defense system has passed seven out of 12 hit-to-kill tests. But in the six years since President George W. Bush pushed for deployment to counter North Korean missiles, only two of the ground-based interceptor tests have been successful.
There have been exactly two GBMD intercept tests during that time (2006 and 2007 (pdfs)), so the fact that “only two” were successful isn’t exactly a mixed record. One might criticize them for lack of testing, but that’s an entirely different critique. (Full-fledged intercept tests are very expensive, so they run a lot more tracking tests (pdf) and so forth.)

POSTSCRIPT: Popular Mechanics links a Time article that argues the Obama administration will continue the program. I sure hope so.
