The proverbial alien beamed down to Earth would find the situation quizzical indeed: The political debates and campaigns involved in selecting the most powerful person on the planet—the US president—scarcely mention the stark fact that any president could at any time be called to decide, almost instantly, whether to order a nuclear attack that would lead to the end of civilization and, possibly, the human species.

It’s time to jettison Nuclear Posture Reviews

Since the end of the Cold War, there have been four Nuclear Posture Reviews (NPRs). Should there be a fifth? No. It’s time to move on. Despite their many virtues, these reviews are not delivering what the nation needs. Indeed, the entire policy and posture review architecture of which the NPR is a part needs … Continued

Cool your jets: Some perspective on the hyping of hypersonic weapons
