Public Radio International's The World has reported that the U.S. military now recognizes "cyber war" as the "new fifth domain of war between states, after air, land, sea and outer space." It reported "the humanitarian consequences of a cyber attack could include damage to infrastructure like power grids and toxic waste facilities," which could, of course, include atomic reactors and high-level radioactive waste storage pools. Bennett Ramberg warned more than 25 years ago that reactors and radioactive waste could be targeted during war, in his book Nuclear Power Plants as Weapons for the Enemy: An Unrecognized Military Peril. The Stuxnet computer worm, targeted at the Iranian uranium enrichment facilities, is rumored to have been launched by the U.S. and/or Israeli militaries, although no radioactivity releases to the environment from the resulting damage were reported.
