What do people think of My Lai?

I do not condone the My Lai atrocity . The only way I can even try to understand it, is the men and it's leader Lt. Calley were under such a burden and constant battle fatigue that something broke down in them that they commited acts that were dispicable under normal cirstances. As an American and a Vietnam vet this still makes me sick ! As a side note the moral and discipline of this unit was terrible, I became friends with a member of the Americal Div. and he was so stressed out mentally that he had lost contact with reality! War changes people in ways that normal person cannot understand.. Calley brought disgrace to our military and should have gotten far much more punishment than he did!
