"In any event, the poster "poohbah", who claims to have some working knowledge on these nuclear devices was pinged to this thread and asked if these devices, in light of their age, would still be functional. His rather succinct answer was "no"."

They are to my knowledge maintenance intensive to keep them operational. If OBL/al-Zawahiri secured technical support (readily available in the former-USSR and elsewhere for a price) then they could have several operational devices.

Yes. I read that the "nuclear walmart" came with tech support.
