You are correct. However, the psychological effect is likely to be an order of magnitude more shocking than 9/11.

Well, if it does, we can thank media fear-mongering. I mean, the very title of the article ("Think Hiroshima") is grossly misleading, gross misuse of language, and pure propaganda. A "nuclear" bomb is correctly one that derives its explosive force from nuclear chain reactions--either fission or fusion. The use of "nuclear" to describe a rad-waste chemical bomb, and to connect such a weapon to Hiroshima is GROSS PROPAGANDA, and nothing else.
