Rest in Peace Shipmate, we now have the watch.
Nothing wrong with that. I am still in wonderment at the left's perverse and weird false altruism of being ashamed of their country, and rooting against its success.
While I do not know your father’s ethnic make-up, I will comment on the fact that many older American Japanese who lived on American soil still despise what happened to them during the war. And we must remember that many American Japanese volunteered to serve in the military while knowing their families were locked up in our version of Concentration Camps.
I think my dad's feeling towards the Japanese was due to the fact that there were negotiations underway at the time of the attack, and the negotiations were seeming to be going well. It is possible the Japanese negotiating team did not know war was imminent. He thought, based upon this negotiating/sneak attack tactic, they were not trustworthy.
One of the reasons for the internment camps was that there was a fear of sabotage by ethnic Japanese. That was definitely a concern in Hawaii, and there were reports of sabotage during or after the Pearl attack. I have not seen actual confirmation that there definitely was sabotage, though I have looked for evidence.
The camps were internment camps, not concentration camps. Big difference. I don't think anyone was starved or executed in these camps.
I have yet to encounter any of the bitterness you have described felt by Japanese Americans due to the wartime incarcerations, but I am sure it exists.
