Although it is off topic, it is hard to leave this thread without some statistics ...
Here are a few of them:
82% of veterans who saw heavy combat strongly believe the war was lost because of a lack of political will.
2.59 million Americas saw service in Vietnam
The US flew 1,899,688 sorties and dropped 6,727,084 tons bombs on Indo China, compared with the 270,000 tons of bombs dropped on Germany during the Second World War
3,500,000 acres of Vietnam was sprayed with 19 million gallons of Defoliants. the effects that will last 100 years.
352 Billion Dollars (US) spent on the war
The full list including atrocities committed by both sides is also available online to anyone with a modicum of computer skills
as is the staggering amount of money spent by Russia and China supporting the Vietnamese.
I guess the Vietnamese did win the war with propaganda and outside support, they certainly lacked the ability to retaliate. I find it staggering that Australians supported this madness and I do have trouble understanding that some still believe this was a "just" war.
