This is the disgusting truth about the anti-war movement... their prejudice that the US and its soldiers are inherently, inevitably bad, criminals, and bound to be doing wrong. This woman should be celebrating what her brave son is doing, especially having rejected all the cr*p that he had been spoon-fed by her and the kid's professors at those knee-jerk "liberal" (communist-leaning) schools in California.
This young man is helping to liberate and give freedom to millions of Iraqis -- tens of millions if you consider the future generations who will be blessed by this liberation in 2003-4. That is more "goodness" than any of these anti-war activists could ever imagine doing, even in their wildest left-leaning imaginations.
It's called "projection", and it's as apparent in the anti-war movement as it is in the "environmental" movement: the end justifies the means. So believing that man does not have a noble side because she can't find one in herself is perfectly reasonable to her.
Simply a form of intellectual infantilism.
