In the lead up to the Nuclear Nonproliferation Treaty Review Conference (NPT RevCon, for those who enjoy acronyms), opening today, the U.S. Bureau of International Security and Nonproliferation released a fact sheet titled “Myths and Facts Regarding the Nuclear Nonproliferation Treaty and Regime.”

A Tough Week for Missile Defense Advocates

It’s not the easiest of times for national missile defense advocates. The normally friendly House Armed Services Committee hearings on missile defense hosted some tough talk centered around a recently released, critical memo from two of the Joint Chiefs.
