@deinol@satsuma I don't think one's an answer to the other, really. Heinlein (in ST) is writing about post-WWII police actions that he wasn't involved in; Haldeman is writing about Vietnam that he was. That alone would give you a completely different set of assumptions, and then there are their individual personalities, and so on. To me they both have value, and I don't reread either very often.
