If these are tritium devices the mafioso are laughing their a__es off. Nothing is harder to make or come by.
This is why it is credible to think that they might have actually sold them -- they thought they were taking in a sucker.
Tritium is VERY expensive and very hard to come by. My biggest fear is that Al Qaeda could have cut a deal with Pakistan to represent them as middlemen in obtaining a supply from Russia for Pakistan's nuclear program. Pakistan is trying to build as many nukes as possible as quickly as possible, and tritium is surely a key limiting factor -- perhaps THE limiting factor. Surely Pakistan would like to obtain a supplemental supply and would pay well for it. At the same time, it would be advantageous to use a middleman so that there would be some deniability. If Al Qaeda operated in such a role, it would be very easy for them to skim off a little of the tritium to use for their own purposes. If this happened, we are in deep danger.
