Can’t be repeated often enough that Viet Nam was NOT “winnable.” I remember when this alternative-truth canard appeared and I was astonished how flimsy it was. There was no “if we had done this and this and this, then this would have happened.” Instead, the whole point was to establish “We lost Viet Nam because of protesters! Shriek!”
It was reminiscent of Nixon’s evil nonsense that, just because he was now POTUS, the same failed strategies would magically start to work in Viet Nam. I think the sheer pain of confronting how many lives were wasted for years helps explain why the empty “protesters did it!” caught on.
The only shred of rationale ever offered was that “well, if we’d just kept at it for five years (or 15 years) ((or 15,000 years)), of course we would have won.” The darkest side lurking behind all this was, of course, “we shoulda just nuked ’em flat and be done with it.”
I’d been amazed to discover nonsense that was going over as plausible before. But this is the earliest, most insidious alt-reality I can remember at the foundations.
