I'm sorry for this lady's loss, but in her grief she forgot that her son was killed by the enemy. No one else is responsible for her loss. I've seen this sort of reaction before in other grieving parents.
No one twisted her son's arm to go into the armed forces. I'm starting to wonder if this lady is your typical sixties moonbat liberal. Perhaps she raised her son on a steady diet of America-bashing, and he joined the army to get away from that stuff.
On Wolf's show she said that her son knew that she did not support the war. She said that he did not support the war, but did support his buddies.
Imagine sending a son to a war zone without giving him unequivocal support. YUK!!
