My significant other's father ... absolutely hated any oriental...
Completely understandable to me. To this day I have no use for the Vietnamese. It is beyond my comprehension why old soldiers would want to go back to Vietnam to visit. Even though I really liked the physical country, all I would be able to see if I went there is a target rich environment.
I'd probably loose what little of my mind I have left.
More recently, wasn't there a trooper that got in lots of trouble because he pissed on the body of a dead Taliban or whatever? 
In actuality they were defending their country from foreign invaders sent by the Washington elites. About 58,000 Americans were killed in an orchestraed political war, where the victims of the war, were on both sides.

Like Korea, Iraq, and Afghanistan, it was a war that should not have ever happened.
And I don't know why any veteran of that war would want to go back either Richard.
