what makes something a "weapon"?
the category exists only as a human thought, and that thought may or may not lead to an action.
Even with a nuke, there is nothing which specifically defines it as a "weapon" it is merely a particularly effective explosive charge (and far, far to expensive to produce for it to have many economic uses - although both the Soviets and the united state did play with the idea of using nukes in civil engineering).
