Siegfried Hecker and Scott Sagan published new essays on the North Korean nuclear crisis. In his article in the Bulletin of the Atomic Scientists, Hecker said, "we need the political equivalent of control rods, which get inserted into a nuclear reactor core to prevent a runaway catastrophic reaction." Sagan, in a Foreign Affairs magazine essay, urges a deterrence strategy for the U.S., because, "when it comes to the current conflict with North Korea, that means admitting that there are no military options that do not risk starting the most destructive war since 1945."
