Well, the counter argument is that by this logic nobody can talk about human rights. Until very recently in human history the Europeans brutally conquered half the world and effectively turned the "savage people" that were unlucky enough to survive the raping and the pillaging into slaves. Listening to anyone who points out legitimate human rights violations is better than listening to no one who points out legitimate human rights violations. It's just more constructive this way.

Killing ten Iraqis to save an American soldier is not justifiable, any which way you look at it.

This is rhetoric, and isn't an interesting statement about what happened in this video, how it was handled by the military, or how it was marketed and leaked by wikileaks. What possible constructive purpose could this statement serve?
