>But don't they go to a lot of trouble to ensure that conventional charge dowsn't go off except under the correct control? Yes, because even without the nuke it's a respectable sized bomb and you don't want one "just going off" when someone crashes an aircraft or has a missile silo fire or whatever, even more so when it's likely to spray plutonium all over the place which is likely to be an expensive facility or vessel you care about not causing downtime for.
