I find it ironic that he talks about the power of love after ditching the Vietnamese girl he was going to have a future with "the way all men betrayed the women who helped them through the war".
Smearing someone's reputation is probably ok, but only with substantive sources. Otherwise it's far too easy to just throw out a half-truth.
Read the last 7-8 paragraphs. The talk about "the power of love" cheapens what is otherwise a resonating piece. No where else does love (apart from "loving" war) come into play.
