I don't even pretend to be a weapons designer... But one would think that there might be better ways to attack these bunkers than simply blasting away at them with more and more force. Nanites, anyone?

Or burrowing spikes that emit a super powerful EM pulse strong enough to melt aluminum. Ever put a CD in a microwave :)?

One cool thing about this is that it uses current adjustable-yield warheads in stock, thereby not violating the NPR (non proliferation resolution).

The drawback is that it blasts a whole lot of radioactive dust into the air, and not at a very high altitude.

A much larger, say 15-20 megaton warhead, would throw the dust much higher, making it much safer for the Saud...er, the neutral neighbors who wouldn't dream of interfering...

In the case of nuclear bombs, the larger the warhead, the more humane the carnage. Thus we need to develop bigger and better weapons if we are to maintain a humanitarian mindset. Besides, a ground blast crater from a 20MT would make one heck of a cool historical marker for a mosque.
