Actually, it might be better to keep some of that stuff for possible clandestine use by potential or actual friendlies, say, against chaveses or ahmadinejads. it's always good to have an extra layer of deniability.
It may be past it's "freshness date". Add in the likelihood that it's been stored in sub optimum conditions and a good chance that it is not the best quality and they are dealing with explosives that are a little touchy, at best. Not something I would want to transport, store or trust to detonate as advertised.
