Have to take a bye here. Also, a lot depends on true intentions that no one I'm aware of has a good read on yet. I'm also not aware of where they are in having a viable initiation sequence, though that was probably purchased through Khan. Hence, my Parchin comment. It's one thing to know how to do it vs. being able to do it. There's a lot more involved than simply having the material for the pits. I'm assuming they are looking at an implosion device vs a cannon device, otherwise why the secrecy on explosives?
