As a Purple Heart combat veteran of the Vietnam War (1968-69 was my Life in the Year), I'll contend that it was a "police action" only to the politicians. This is about the seemingly unshakable baggage that many who have experienced the exhilarating horrors of combat may recognize.
There is a place
Not on any map of this world
But on the map of the boundless Mind
Where there is danger.
There are familiar places
And there is a line
I went across that line
Everything I had brought with me
And all my cherished belongings
I learned, just soon enough
Standing at port arms like a ready troop.
Watching for signs
Watching for harmless and sunny recollections
He's ready to sound the ALARM!
And this aulde Yankee Air Pirate says
To all me Nam Vet Brudders and Sisters
