Simply put, experts in areas ranging from geology to engineering to warfare concur that a low-tech refuge carved sufficiently deep into rock can withstand assault from even the most sophisticated of 21st-century bombs

Crap ... NORAD was a sitting duck. The Russians had a whole regiment of SS-18 Satan Mod 1's with 25 megaton warheads tasked to it.

If the exchange had come Cheyenne mountain would have gone to Cheyenne Lake.

Yep.... multiple strikes are they way you crack deep targets. Keep slapping them with nasty stuff in the multiple- megaton range until they are mist in the upper atmosphere.

Those SS18 Mod.5's (and the Mod.3's with their 14 550 kiloton MIRVed warheads) are still online, BTW. They scrapped the 25 megaton warhead for a 20 megaton with a better re-entry vehicle that is less vulnerable to counter-measures.

"If the exchange had come Cheyenne mountain would have gone to Cheyenne Lake."

Precisely. This article speaks about a specific (an rather small and lightweight) nuke. He also complains about accuracy, and doesn't mention that the laser guided weapons are nothing more than iron bombs with a laser seeker on front and control surfaces in the back that come as a kit and are "strapped on" during bomb prep. These could be used on nukes as well.
