Another Iranian nuclear scientist was killed today by a magnetic bomb attached to his car. Iran blames the U.S. and/or Israel, but couldn't this have just been an accident? Who hasn't had a magnetic bomb attached to the underside of their car at one time or another?

According to the Washington Post:

Two assailants on a motorcycle attached a magnetic bomb to the car of an Iranian university professor working at a key nuclear facility, killing him and his driver Wednesday, reports said. The slayings suggest a widening covert effort to set back Iran's atomic program.

The attack was similar to a November 2010 explosion which killed one nuclear scientist and wounded another. Which makes the job of nuclear scientist the second-most-dangerous in the world, after the guys at the zoo who have to reach in and grab out pieces of food that gets stuck in hippopotamuses throat. Here is a timeline of all the other bad stuff that's happened, inexplicably, to Iran's nuclear program.
