As I'm sure most of you are aware, the full title of Dr. Strangelove is Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb. Since the movie doesn't seem to be from any one person's point of view, I have to wonder: who is the "I" in the title referring to? I thought maybe it could be President Muffley or General Turgidson. At the end of the movie they are both optimistic about Dr. Strangelove's plan to
survive the nuclear fallout in mineshafts, with a 10:1 woman to man ratio of survivors.
It could also refer General Ripper, since he worries about the Communists contaminating his "precious bodily fluids" and the bomb is his solution.
The main title "Dr Strangelove" is the anglicised version of the name of a German scientist "Dr Merkwürdigliebe" - a reminder of the contribution played in US atomic research, defence, strategic thinking and the space race by ex-Nazi scientists and refugees from Nazism (Werner von Braun, Edward Teller) as well as a suggestion that there is a "strange" link between sex/love and killing/death - a "pornography of power".
The subtitle is a reference to the immediate period after the Cuban Missile Crisis when military planners, politicians and ordinary people accepted the fact that they could and would have to learn to live with the threat of nuclear wa for the rest of the Cold War.
So basically nobody. Or everybody. Take your pick.
