Other news reports indicate that Israel has already received
the 30K MOPs; that O told Netanyahu the MOPs may not destroy the underground facilities; the alternative is to seal the shafts and entries into the facilities and slowly kill off the occupants.
BTW O inherited the improved MOPs from Bush.
My understanding is Iran uses a special type concrete. Harder than the norm. Built to withstand earthquakes. Natural and “man-made...”
The MOP is an enormous weapon that only the B-2 and the B-52 can carry after special modifications. Israel does not have a single aircraft that can carry the MOP. Not even our own B-1 bombers can carry the MOP since its three bays are segmented and don’t have enough space to hold the long and heavy MOP.
