....my late dad was in the Signal Corps stationed in the Pacific during WWII...never really spoke much about his experiences there....he caught some kind of “crud” (what he called it) there and years and years afterward, from time to time it would manifest itself as a rash or something on his arms and legs...could never get rid of it....he hated the idea that Americans were so fond of driving Toyotas, Nissans (formerly Datsuns), Hondas, Subarus, etc....”the Japs really won that war”...he would say....
My uncle, dad’s oldest brother was a marine in the Pacific. On Okinawa, he was pinned under a jeep with broken hips and broken legs, and a Japanese patrol bay, and added him through his throat while he lay there trapped.
He lived amazingly enough. Hated the Japanese for the rest of his life.
Pretty sure he would’ve agreed with your dad.
