PRY: If Iran already has the bomb, what then? - Washington Times: "If the same small nuclear weapon postulated in the White House planning guide is launched to high-altitude over the United States, perhaps fired from a freighter operating off the U.S. coast, the resulting electromagnetic pulse (EMP) could collapse the national electric grid and other critical infrastructures that sustain our modern society. The Congressional EMP Commission warned in 2008 that, given our current state of unpreparedness, an EMP attack by rogue states or terrorists could kill millions of Americans from starvation, disease and societal collapse."
