This "write a letter to a soldier campaign" is a little different from the ones you usually hear about.

Write a letter to a soldier to let him/her know what people really think of this war. Send a photo of a dead Iraqi civilian. Send a photo or message about an anti-war protest.

I found this organization Soldiers Angels maybe there are others. Outreach to soldiers is the best way to persuade them to stop killing civilians. Maybe they will even begin fragging (killing their officers) like in Vietnam. It's worth a try.
