I know we all share this sentiment but it isn’t something a US Marine should do. Marines hold themselves to a higher standard.
Marines are human. This isn't some academic exercise, it is real war. If you think the Marines fought the Japanese in the Pacific showing some great respect for Japanese bodies, you are sadly mistaken. And I can tell you from firsthand experience in Vietnam, that was not the case. When someone is trying to kill you and your buddies, you could care less about how their corpses are treated.
I had the honor of serving with a Marine hero, Sgt. Lew Hirschman. He served in China with the 4th Marines and another Marine legend, Lou Diamond. Lew was told to march several Japanese POWs captured in one of many battles he was in. He marched them out of sight and promptly shot them. An officer threatened to have him court-martialed and Lew told him bluntly: “Payback for the Maryland”. Lew had lost several friends on the USS Maryland at Pearl Harbor.
Maybe this was unnecessary, but walk a mile in their shoes before criticizing.
