if one had a time machine, one could go back in time to before the vietnam war. and find out what would have happened if we had overcome our fear of communism and honored fair and free elections. even if it almost certainly meant the commies would win. probably a lot of people would have died in the aftermath. but a lot of people died anyway. given the latter lot is in the millions, one can reasonably guess the former lot would be somewhat smaller. and vietnam would be peaceful and prosperous decades sooner. but we lacked the courage to face down our fear of communism. which was a lot worse than the communism itself. and we don't have a time machine. so jeff miller, allison krause, william schroeder, and sandra sheuerer will stay dead.
