I didn’t mean to imply that I did.
But I was trained for it, and I expect that if things had got so desperate that anyone was stupid enough to send me there then I would have done what I was trained to do. And, at the time, what I thought was the right thing to do.
Yeat it would be right thing.
Anyway that, why have not you been disillusionmented in Capitalism when Capitalist Japane attacked Allies?
Why do you think that if Viet Cong attacked you it was guilt of their “Socialism” ( that indeed was rather military kind of National-Bolshevism at that time).
You know that the Socialist USSR fought against the Communist Chinas in late 1960 pretty well.
And their “communist” was quite different or our one.
No, it would have been the wrong thing. We should never have been there. But I and most other Australians didn’t see that until near or after the end of our involvement. Some still haven’t seen it.
I have long been disillusioned with aspects of capitalism, but compared with the alternatives that have been tried at various times it’s the best system so far, as long as it’s combined with a reasonably social democratic type of government and society of the type common in Western Europe, Britain, Australia, New Zealand and so on.
Most of the best wars in history have been fought between capitalist nations. In fact, there has yet to be a decent war between a capitalist and communist nation. And given that Russia and China are now capitalist nations, with the worst type of largely unregulated capitalism in China and not much better in Russia, it looks like we’ve missed our chance. 
The Viet Cong, and North Vietnam, never attacked me, Australia, America (the alleged Gulf of Tonkin incident nothwithstanding), Korea, or New Zealand, all of which had troops in South Vietnam fighting valianty to uphold a corrupt South Vietnam regime.
I’m with Muhammed Ali in keeping out of something that had nothing to do with us, who on explaining his reasons for conscientious objection to the draft said ‘No Viet Cong ever called me nigger.’ Although at the time, to my shame, I thought he was just trying to avoid war service.
Nationalism and national liberation explains the different types of socialism and communism which appeared in Vietnam and other former colonial countries. Russia and China had different histories and produced their own forms.
Which was a bit of a bugger for commies down here in the 1950s to 1980s as some of the most bitter battles were fought between the Moscow aligned and Peking aligned commies, with the Trotskyists always opposed to both, and vice versa. If the commies couldn’t agree among themselves in a liberal democracy, what hope did they have trying to run their own state or international alliance?
