As a former RAF nuclear bomber technician, yes, I've seen nuclear bombs. They are pointy at one end, and have fins at the blunt end. Fortunately, I've never seen a nuclear explosion, however.
I've also seen conventional high explosive bombs. They are also pointy at one end, fins, etc. Unfortunately I've never seen one of those explode either, but have spoken to friends who have seen them explode.
I've also seen air-to-air missiles. They are kind of bomb-shaped (pointy, fins etc), but much, much thinner. Fortunately, I HAVE seen missiles fire and explode.
On the basis that I have witnessed the function of missiles, been assured of the function of conventional bombs, and personally seen nuclear bombs, I have every reason to believe that they will explode in a nuclear manner as described in the brochure, should we decide to smite our enemies in such a manner.
