The planning in the film, by Dr. Strangelove, done the MAD policy has clearly broken down, to keep the human race alive and to regenerate from populations sheltered in mineshafts, is a parody of those strict adherents of the MAD doctrine who are opposed to the prior creation of fallout shelters on ideological grounds. To such adherents, talk of survival takes the "Assured Destruction" out of "Mutual Assured Destruction", hence no preparations should be conducted for fear of "destabilizing" the MAD doctrine. Moreover, it is also somewhat of a parody of Nelson Rockefeller, Edward Teller, Herman Kahn, and Chet Holifield's November 1961 popularization of a similar plan to spend billions of dollars on a nationwide network of highly protective concrete-lined underground fallout shelters, capable of holding millions of people and to be built any such nuclear exchange began. These extensive and therefore wildly expensive preparations were the fullest conceivable implementation of President Kennedy's, month prior, September 1961 advocacy in favor of the comparatively more modest, individual and community fallout shelters, as it appeared in "Life" magazine, which was in the context of shelters being on the minds of the public at the time due to the Berlin Crisis. The Kennedy administration would later go on to expand the nascent United States civil defense efforts, including the assessment of millions of homes and to create a network of thousands of well known, black and yellow placarded, community fallout shelters. This was done, not with a massive construction effort but by the relatively cheap re-purposing of existing buildings and stocking them with CD V-700 geiger counters etc. In 1962 the Kennedy administration would found the American Civil Defense Association to organize this, comparatively far more cost-effective, shelter effort.
