I wonder if that was part of a "moral" that developed as the series evolved? That no matter how horrifying things become, mankind nonetheless has only one ultimate answer--the same answer, repeated over and over--war and destruction. Was that ultimately why the characters were stereotypes? Because in pursuing just one answer we fall into expected patterns of behavior guaranteed to provide the certain outcome of conflict? Because questioning ourselves is not enough (Roger Smith); we must also question our society and our place in it (Dorothy)?
