I know John Kerry listened. This was part of his famous testimony to the SFRC in April of '71.
We found also that all too often American men were dying in those rice paddies for want of support from their allies. We saw first hand how money from American taxes was used for a corrupt dictatorial regime. We saw that many people in this country had a one-sided idea of who was kept free by our flag, as blacks provided the highest percentage of casualties. We saw Vietnam ravaged equally by American bombs as well as by search and destroy missions, as well as by Vietcong terrorism, and yet we listened while this country tried to blame all of the havoc on the Vietcong.
We rationalized destroying villages in order to save them. We saw America lose her sense of morality as she accepted very coolly a My Lai and refused to give up the image of American soldiers who hand out chocolate bars and chewing gum.
We learned the meaning of free fire zones, shooting anything that moves, and we watched while America placed a cheapness on the lives of Orientals.
We watched the U.S. falsification of body counts, in fact the glorification of body counts. We listened while month after month we were told the back of the enemy was about to break. We fought using weapons against "oriental human beings," with quotation marks around that. We fought using weapons against those people which I do not believe this country would dream of using were we fighting in the European theater or let us say a non-third-world people theater, and so we watched while men charged up hills because a general said that hill has to be taken, and after losing one platoon or two platoons they marched away to leave the high for the reoccupation by the North Vietnamese because we watched pride allow the most unimportant of battles to be blown into extravaganzas, because we couldn't lose, and we couldn't retreat, and because it didn't matter how many American bodies were lost to prove that point. And so there were Hamburger Hills and Khe Sanhs and Hill 881's and Fire Base 6's and so many others.
