100 groups "have the bomb" and not a single "bomb" has gone off accidentally?

Sorry, uh uh, don't buy it. These terrorists are notorious for blowing themselves up trying to put bombs together.

100 groups "have the bomb" and not a single "bomb" has gone off accidentally?

And none of them have tested one to make sure a) they work, and b) they know how to operate them?

I don't know a whole lot about this, but I believe it is difficult to set off a nuclear weapon. So, the accidentally blowing themselves up scenario is not likely. But the accidentally contaminating themseleves and their neighbors scenario would seem to be more likely.
