In 1968, three US soldiers ended the My Lai massacre. They were ready to shoot the murderous soldiers if necessary, to protect the Vietnamese civilians that were still alive.

My father was disgusted when he learned of the My Lai massacre. It reminded him of Nazi behavior. So he printed stickers (he owned a printing company) with a list of the locations of a few well-known German massacres in World War II, with My Lai added at the end. This was what first led me to think about the issue of war crimes.

The US suffered a moral injury from committing the My Lai massacre and then protecting the guilty.
