Dear Editor, It was American mothers who were the catalyst for our withdrawal from Vietnam, and once again it is mothers leading the turn in public sentiment against the Iraq war [“Sheehan's Field of Dreams,” News, Aug. 19].

Recent history in mind, it seems that it will take someone other than a male politician to value the lives of our nation's youth.
