Inside DARPA’s competition to build a better humanitarian-assistance and disaster-relief robot.

Since the early 1990s, the nonproliferation community has obsessed over the annual appropriations to programs at the US defense, state, and energy departments that are designed to keep weapons of mass destruction (WMD) out of the wrong hands.

En la primera ronda, mis colegas y yo concordamos ampliamente en que la detonación nuclear, ya sea deliberada o accidental, afectaría a Estados e individuos de manera muy seria, y este daño no se detendría en las fronteras. La historia lo corrobora: las detonaciones en el pasado han traído consecuencias desastrosas, tanto de manera inmediata, … Continued
