To really appreciate this movie, it has to be seen in context. After you watch it, watch the movie "Fail Safe", and then watch "Dr. Strangelove". You can see how America began to doubt its leadership as the Vietnam crisis deepened...It's almost a history course on the Cold War, and it goes from patriotic to scary to ridiculous. America goes from a "bomb shelter in every basement" to "How I learned to stop worrying and love the bomb" (the subtitle for Dr.Strangelove".) Or, from Jimmy Stewart, to Henry Fonda and Larry Hagman, to Peter Sellers and George C. Scott. All of whom provide outstanding performances in their respective roles. Seeing these films in order makes sense of all of them.
