Feel better now that you've vented.
Look I don't know who you are or where you're from, I am getting an Idea of what you're like.
Keep this in the back of your mind. For many of us this isn't ancient history. It's history that we lived.
Well, doh. Why do you think I used the pjrase "In my lifetime"?
No I wasn't in Vietnam, I lucked out as they stopped drafting people 2 months before I was 18.
I remember my friends older brothers coming home in a box, or in a wheelchair for life or just very strange for a number of years. You have declined to state where you are from, are you afraid that we will dump on where you live. Not that I really care. Get over yourself.
Actually I was too busy explaining stuff that actually matters to you. Which you obviously failed to comprehend. Because "This happened in my lifetime" is not a morally adequate excuse for morally trivializing genocide - we don't say to Germans; "Hey, you lived through WW2 and had friends of friends hurt - make all the hate films about Evil Jews and how you should have won WW2 that you want!!!"
Yes, it sucks to be in a wheelchair. But also: man the fuck up! Millions of Vietnamese - often children - were murdered. The suffering of USians is tiny by comparison, and it was a war that America chose to inflict on the Vietnamese. For you, the barely injured aggressor, to demand that your comparatively minimal suffering means that facts should be distorted is unacceptable. If you don't want to read honest threads on Vietnam, simply don't have any or avoid the ones that occur.
And I'm British - and note that, no, we did not find it necessary to, ohhh, kill a quarter of the population of Ireland over the "Troubles". And we don't have any popular movies showing how Irish people are evil (as opposed to beer companies who promote St Patrick's Day) and that therefore we should have killed another million or so.
Quite simply: KILLING SEVERAL MILLION PEOPLE FOR NO REASON OTHER THAN THEY WOULD NOT DO WHAT YOU WANTED IS EVIL. And the more people you murder this way, the fewer friends you would have. If you want to know what the effects of using more violence in Vietnam would be then
1. You'd be despised
2. If you won, then you would have to keep a Vietnamese dictatorship in power, using US troops, forever - because the Viets would hate you and elect an anti-US government as soon as they got the chance
3. The Chinese and the Russians would be welded at the hip
..You might well reach a point - eg the Arab oil oil embargo - when the US's allies repudiate it completely. Meantime in the USA you'd have hundreds of thousands of troops who'd been trained to in brutal repression. Not great! You could have a nice timeline where the USSR Glasnosts earlier and the US is isolated and then becomes a quasi-dictatorship.
