Hugh Pickens writes "The New York Times reports that President Obama's plans for reducing America's nuclear arsenal and defeating Iran's missiles rely heavily on a new generation of antimissile defenses which last year he called 'proven and effective.' Now a new analysis being published by two antimissile critics at MIT and Cornell casts doubt on the reliability of the SM-3 rocket-powered interceptor. The Pentagon asserts that the SM-3, or Standard Missile 3, had intercepted 84 percent of incoming targets in tests. But a re-examination of results from 10 of those apparently successful tests by Theodore A. Postol and George N. Lewis finds only one or two successful intercepts, for a success rate of 10 to 20 percent. Most of the approaching warheads, they say, would have been knocked off course but not destroyed, and while that might work against a conventionally armed missile, it suggests that a nuclear warhead might still detonate. 'The system is highly fragile and brittle and will intercept warheads only by accident, if ever,' says Dr. Postol, a former Pentagon science adviser who forcefully criticized the performance of the Patriot antimissile system in the 1991 Persian Gulf war. Dr. Postol says the SM-3 interceptor must shatter the warhead directly, and public statements of the Pentagon agency seem to suggest that it agrees. In combat, the scientists added, 'the warhead would have not been destroyed, but would have continued toward the target.'"

figona brings news that India will be allowed to join the Nuclear Suppliers Group (NSG). A waiver was approved yesterday that provided an exception to the requirements that India sign the Nuclear Non-Proliferation Treaty and the Comprehensive Nuclear Test-Ban Treaty. This means India will be able to buy nuclear fuel from the world market and purchase reactors from the US, France, and Russia; something it has been unable to do since it began nuclear testing in 1974 (which inspired the creation of the NSG). The waiver does not include terms to cut off access if India resumes nuclear testing, but the US Congress drafted a letter stating their willingness to do so. Opponents of the waiver have called it a "non-proliferation disaster."
