Tom Paxton says that he was brought to tears by a letter a vietnam vet sent to him, telling him that the vet had his own Jimmy Newman...and that the irony was that the previous night they were discussing another one of Paxton's songs..

as for anti war...well there is Jacob's Ladder (Not In MY Name) by Chumbawamba...i really love the line sooner or later puppy dog leader we'll try you for murder....

and there is bogle's As If They Know...about the horses that were sent to world war one...but never came back...

and though not really anti war...but anti a unfortunate side effect of the red necked paranoia of war...there is Manzanar...about the Japanese being imprisoned by the State...for being Japanese...
