There doesn't seem to be much info on his project. He refers to "(his) National Aimpoints List" which actually is a PDF copy of the Nuclear Attack Planning Base-1990 National Aimpoint List made from the document that was acquired via interlibrary loan. According to this source, the singular copy of it currently resides at the National Emergency Training Center Library. My guess is that, post 9/11 it wasn't reclassified, but put on the list of things that they won't let you see...just because.
It's (IIRC) 9000 lines of latitude and longitude coordinates (accurate to the minute), along with yield, HOB, target classification (MIL, POLIT, POWER, CHEM, OTHER), and overpressure radii. It's in such poor condition that there's no way to OCR it back into the computer. It has to be done manually. It's tedious work. But, it was the computer model on which the NAPB-90 report is based.
I don't disagree with you about the concept of completely eliminating nuclear weapons--as a realist, I think it's a fantasy anyway for lots of reasons--but I am coming to question the iron-clad notion of nuclear deterrence a bit. At the moment, I'm reading an interesting book titled 5 Myths About Nuclear Weapons which gets into the details about the sort of 'received wisdom' about how the world works under the nuclear umbrella, and, although I'm not entirely convinced about the author's conclusions, I'm beginning to see some of his points.
Of course, I would very much like to believe in the notion that nuclear weapons provide security, but there's also the fear that, even if deterrence is iron-clad rock solid, it can still be undermined by technical malfunction, accident, or terrorists who don't have anything to protect.
