Input: This book is a collection of stories and observations on American foreign policy from the perspective (in this case liberal) of some students attending Dartmouth during the Vietnam War. The title infers that these students were critical thinkers, perhaps even revolutionaries. Although they were, in reality, largely just ordinary liberal pacifists who had little interest or opportunity to challenge either the war itself or US strategy.
Output:
Good Review
