In the 1960's was this film a phenomenon singular to America, or were there other film makers/writers/famous figures overseas that poked fun at the extreme tensions and "perfect rationality" of MAD? Were contemporaries of Kubrick overseas also lampooning MAD, or was Dr. Strangelove unique in it's dark comedy? I think my question boiled down is "was there any measurable international reaction to what can be viewed as cavalier Americans making jokes about humanity's demise as they played the active role in that same hypothetical destruction, or did the film have overseas competition in getting a laugh out of the zaniness of it all?"
My research has consisted of googling this question 85 different ways, and I haven't turned up anything interesting, ...probably due to user error. Thanks for any answers!
