This excerpt, for me, was the most powerful part of the story:
What would happen if the nation openly acknowledged the casualty gap? Would citizens rethink questions of war and peace? To find out, we conducted a series of original public opinion survey experiments with nationally representative samples of Americans. We found that citizens informed about the existence of a casualty gap were significantly more likely to oppose ongoing military operations and less willing to support future ones than were their peers who were not informed about casualty inequalities.
The editorial comes on the very day we learn that more than 1,000 American soldiers have died while fighting in Afghanistan.
