This topic has been discussed a lot, here's a good article:

There are threats which even though they have weapon potential are not used anyway.

There was tons of FUD from Greenpeace about terrorists blowing up nuclear power plant for decades. In reality the only person who ever did that was Green activist idiot, Chaim Nissim, who shot reactor in construction from an RPG to demonstrate the threat is real. He didn't even scratch it, and nobody ever repeated it.
