I find the headline to be a little misleading.
It makes it seem like Palin is demanding another country apologize, which would be weird since she is a private citizen whose demands like that would be silly. Instead her post is just reasonably pointing out that Afghan Army should apologize for their murders.
I agree. I was aghast when I first saw the headline without reading the text.
If it’s murder they should arrest the perps, try them and then serve them appropriate sentences.
Let’s remember words have meaning. If you are inclined to call it murder, then justice through the law should be applied.
