An interview with Thomas Schelling and his role in the creation of one of my favorite movies, “Dr. Strangelove”. HKS reports,

Kubrick travelled to Cambridge to meet with Schelling and George. The three spent an afternoon wrestling with a considerable plot hole: when “Red Alert” was written in 1958, inter-continental ballistic missiles were not much of a consideration in a potential U.S.-Soviet showdown. But by 1962, ICBMs had made much of the book’s plot points impossible. The speed at which a missile strike could occur would offer no time for the plot to unfold. “We had a hard time getting a war started,” said Schelling.

Hence, the B52s?
