I mentioned the late JB Lenoir's Vietnam Blues previously in this thread.

Here are the lyrics ... I think this song says it all.

"Vietnam Vietnam, everybody cryin' about Vietnam
Vietnam Vietnam, everybody cryin' about Vietnam
The law all the days (?) killing me down in Mississippi, nobody seems to give a damn

Oh God if you can hear my prayer now, please help my brothers over in Vietnam
Oh God if you can hear my prayer now, please help my brothers over in Vietnam
The poor boys fightin', killin' and hidin' all in holes,
Maybe killin' their own brother, they do not know

Mister President you always cry about peace, but you must clean up your house before you leave
Oh how you cry about peace, but you must clean up your house before you leave
How can you tell the world how we need peace, and you still mistreat and killin' poor me."
