On this Memorial Day weekend, I give thanks for Hugh Thompson, Jr., Glenn Andreotta, and Lawrence Colburn, who courageously and properly said “no” in the face of misguided fellow soldiers and superiors.

When I hear someone say “thank you for your service” to a member of the military, I think of these three, who embodied the best of what “service to your country” is, in the face of others who embodied that service at its worst.
