The really useful explosives don't go off because of rough handling and don't become unstable over time - both very desirable properties to prevent handling accidents. Ideally, the fuse is the only thing capable of setting it off. So hopefully, the explosive will just sit there in it's shell and stay inert. Most WW II duds are dangerous because of their fuses, not the bulk explosives, as I understand it.
