He was at pearl harbor when it was bombed, he was in a submarine under Tokyo bay during the war, he was part of many battles in the pacific, and finally nearly killed in a collision and received the purple heart among other medals. He was then part of the occupation of Japan after the war.
What did he decide to teach me after all that?
That the Japanese people are/were good people that were fooled and otherwise coerced (forced) into the war by evil leaders. Much like Russia today.
I've carried this with me my whole life. And will continue to try to spread it around (compassion).
