As I recall, North Vietnam infiltrated and attempted to invade South Vietnam, in violation of international law, an ally we had a treaty obligation to defend.[...]
Our treaty obligation was to defend the nation of Vietnam against aggression by anti-Western powers. Vietnam was
not attacked by any foreign power. Vietnam was engaged in a
civil war. There were no foreign troops on that soil -- except ours! Technically and legally we had no business interfering in that civil war! And that is the "mistake" Robert MacNamara finally got around to admitting we made in getting involved there.
All I have to say about your declared willingness to go there under arms and the absence of any regret is you're lucky you're not in a wheelchair today, or worse. Because if you were you either would be singing a different tune or you would be considered mentally defective. And I tell you this because as a protester I met several disabled vets who were crippled in Vietnam and I will wager heavily that none of them have your cavalier attitude -- especially the one who had half his face burned off.
What for??
In case you forgot, the RVN was INVADED by North Vietnam. Not only were a lot of the VC actually members of the PAVN (North Vietnamese Army) infiltrated into South Vietnam (a fact they often willingly admitted to, when captured),
there were uniformed NVA units operating openly in South Vietnam, in regimental and even division strength, even as their government lied about it to the world. After we pulled out following the Paris Accord, the NVA openly invaded and eventually conquered South Vietnam, something they had pledged NOT to do under the Paris agreement. Vietnam was NOT a civil war; it was an act of naked aggression by one sovereign nation (acting as a proxy for the Soviet Union) against another, and THAT is what we were fighting to stop.
A lot of good men died in Vietnam; some of them were my friends, some of them were my own men, who I could not bring safely home to their families,; ALL of them were my brothers. More have died since; some by their own hand, some from the effects of Agent Orange; but in plain truth, what really killed them was indifference and neglect here at home. Many others will never walk again, are missing arms and legs, or lost their sight. Many of us have battled what we now call PTSD, and all of us will go to our graves carrying the memories of what we saw and had to do. The price of duty and honor is steep. The cost of defending freedom (our own and/or someone else's) is high. You are right on one thing; I AM one of the lucky ones; I made it home with all of my body parts mostly intact; but in the end, all of us, whether our wounds are obvious, or mostly invisible, have had to ask what we did it for.
We did it to protect the people of a little country halfway around the world from a neighborhood bully next door. We did it, because we swore an oath. We did it, because we loved our country, and she called us; and in the end, we did it for each other, because in the worst of it, each other was all we had. You may not understand any of that, but the fact is that the overwhelming majority of us would do it again, even knowing what price we would pay; the horror and the heartbreak, the grief, the pain, and loss; the scars, the suffering, and lives forever changed. Regrets? Of course we have regrets; that the cost was so high, that we had to sacrifice so much, that in the end we were not allowed to save the people we fought so hard to help from oppression, tyranny and atrocity; that too often our own countrymen have vilified us, accusing us of things we didn't do. In spite of all that, we have something else, something that has sustained us through the battle over there, and the battle here at home - the knowledge that we stood for what we believed was right, even when it was not easy or popular, that we did our duty with honor, and shamed neither ourselves nor our country, that we gave our all to something bigger and more important than ourselves. That is something to be proud of, and all the lies and all the hate in the world can never take it from us.
