My dad was a Marine on Okinawa. He once told me that one thing every Marine understood was Japanese never surrender.
My uncle was a Soldier on Okinawa. To this day he despises the Japanese and never talks about his experience other than to say “bad things happen in war. The best you can do is to get over them and move on.”
After I served in Iraq I wish he would talk about before he passes. But I completely understand why he doesn’t and I respect his wishes.
