I think it is you who is stuck believing what you tell yourself. You can't accept that (highly likely) possibility your government simply used you and tossed you aside, exploiting some of the best years of your life. But hey, I guess like your pills and hearing aids.
It was Johnson who got us there because he thought that Kennedy wanted it. Gradually, through his Administration and Nixon's, the far-left contingent of the Democrats got stronger and stronger. Then, after the war was officially over, when the NVA invaded again, it was the Democrats (who as you pointed out controlled Congress) reneged on the agreement to support ARVAN and left them to be slaughtered.
And, as far as my VA benefits, without them, I probably wouldn't need hearing aids because I would have died about a decade ago after I ran out of money to pay for the medicines that keep me alive. Of course, if the government had "tossed me aside" as you claim, they'd have closed the VA or declared all 'Nam vets ineligible instead of providing care for us, but don't let inconvenient facts get in the way of your prejudices.
May you live forever, Ephialtes.
Thank you, but nobody who knows me has ever even considered accusing me of being a radical. I'm just another aging Boomer, who happens to have lived through a section of history that you can't understand any more than I can really understand either World War.
