Terrorism pops up all over science fiction, and last night’s episode of Eleventh Hour was no exception with terrorism featuring VX gas. The plot focused on a group of white converts to Islam (thank you, Hollywood, for reinforcing that stereotype. We’re all painfully aware of the dangers of lunatic jihadists, but let’s not become so fixated on that that we blind ourselves to the fact that as, say, Oklahama and Belfast demonstrated, terrorists can have sorts of religious faiths, including agnostic and Christian, while simultaneously tarring all Muslims with the same brush). The terrorists plan to take over a theater full of kids and hold them hostage. The weapon they intend to hold over their heads is VX nerve gas, more or less considered the deadliest chemical weapon in the world’s arsenals. It’s the same stuff Ed Harris was smuggling in The Rock, and one of the weapons Saddam Hussein used on the Kurds. VX gas is, by most experts’ account, the most deadly chemical weapon yet invented. It’s so potent that when the British invented it in 1952, the Americans were willing to trade away nuclear secrets to learn how to make it.
