Of the millions desperately fleeing the daily terrors of communist rule, countless thousands would perish in the Gulf of Thailand or the South China Sea when their pathetically rickety boats capsized under the their own weight. If those millions of deaths weren't enough to convince you that fighting communism in Southeast Asia was a truly righteous cause, then mere words could never persuade you."
