Sir, if you cannot manage your political idealism, you cannot manage history. The study of History, after all, is the study politics' past with your bias checked at the door. I suppose the Vietnam war is still a little fresh to expect an unbiased view from a layman but I expect more from a lover of history; It's just childish. It genuinely saddens me that these children will leave your lecture believing they've obtained a comprehensive history of the Vietnam war. (For instance, I love how you keep repeating "unified" ..."vietnam just wanted to "unify" ... "after the war, vietnam ended up "unifying" anyway. That sounds so pretty doesn't it?) What a disgrace to the true study of history.
