Planetary defense is the defense of planet Earth against collisions with near-Earth objects (NEOs), which include asteroids, comets and meteoroids. A central objective of planetary defense is to reduce risks to Earth and its inhabitants. Whereas planetary defense is mainly focused on risks from NEO, this paper argues that planetary defense decisions should also account for other risks, especially risks from violent conflict. The paper is based on a talk I gave at the 2019 Planetary …

If an asteroid is found to be on collision course with Earth, it may be possible to deflect it away. One way of deflecting asteroids would be to use nuclear explosives. A nuclear deflection program may reduce the risk of an asteroid collision, but it might also inadvertently increase the risk of nuclear war or other violent conflict. This paper analyzes this potential tradeoff and evaluates its policy implications. The paper is published in …
