You might not believe it but the US military actually places a premium on not committing war crimes. Every service member, or at least every airman in the Air Force (I can't speak for other branches) receives mandatory training on the Kunduz hospital before deployment in an effort to prevent another similar tragedy. If they didn't care, they wouldn't waste thousands of man-hours on it.

I knew a guy whose job was to assess and approve the legality of each strike considering second order impacts on the community

> On 7 October 2015, President Barack Obama issued an apology and announced the United States would be making condolence payments of $6,000 to the families of those killed in the airstrike.

Definitely a premium.

Most importantly they finance propaganda films like "eye in the sky" to make it look like they give a shit about not killing civilians.

Videos on wikileaks tell a different story.
