FWIW, Dr. Strangelove is my all time fav movie. Kubrick was not out to make a happy ending, unless you count 10 women for every man to be a happy ending.
One thing I've been thinking lately is that America has had a paranoia for some time now. During the cold war, we were constantly under the threat of nuclear annhilation. Currently we are in the throes of paranoia of terrorism. I've wondered if such threats is what binds us as a nation, making us driven.
Someday they'll make a dark comedy about our insecurities against the current enemy that will become a classic for another age. May be a while though.
