The Bushwacker conjured up the name of Vietnam to boost his argument for staying on in Iraq. He throws in a few scary phrases, "boat people, education camps, killing fields".
Hang on a minute! Killing fields? That was Cambodia; Pol Pot and the Khmer Rouge. They were enemies of the Vietnamese and allies of - guess who! Why China, USA and UK.
I learned a few expressions from Vietnam before the US forces cut and ran; napalm, Agent Orange, tiger cages, My Lai, carpet-bombing, "barbecued monks".
