Kubrick's next project was "Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb" (1964), another satirical black comedy. Kubrick became preoccupied with the issue of nuclear war as the Cold War unfolded in the 1950s, and even considered moving to Australia because he feared that New York City might be a likely target for the Russians. He studied over 40 military and political research books on the subject and eventually reached the conclusion that "nobody really knew anything and the whole situation was absurd".
