Hanoi's General Giap's "ah ha" moment

A few years after the US pulled out of Vietnam in 1975, General Giap was reported to have said that he now realised what a mistake the Vietnamese army had made in defeating the US. The reason was that the US only helped those it had defeated, like Germany and Japan, but not those who had won!

It was not till 1995, 20 years later that the US and Vietnam restored diplomatic relations and finally US aid and support was forthcoming.
