McGrath, I'm glad you mention the Vietnamese. If it was a psychologically hellish time here in the states, it was a total hell many times over for Vietnam. I think the figures of 1 million soldiers killed, and 2 million civilians killed, are roughly accurate.
General Curtis LeMay said "we should bomb them into the stone age."
It is not well appreciated (insert list of reasons here) that a people who basically still were in the stone age, stood up to an invading Goliath and kept on fighting and fighting for their land, in the face of such terrible casualties. They showed an example that said to the whole world, "It can be done."
One reason for the U.S. campaign of mass destruction, was to send another message to the world: "If you try to resist us, this is what you'll get."
