I figure that the Saudi’s with the clandestine help of the Israeli’s smuggled in a HE a bomb underground that once detonated caused a serious problem. Once the Uranium Hexaflouride breaks down and the HF acid starts to destroy the things the subsequent release of hydrogen gas will further destroy all contained spaces.
Now I would expect the islamonazi’s to send in their special crazies to salvage what’s left.
NO cheers, unfortunately -- I might even pray for the poor bloody sods trapped down there if HF was released...
