Faceless US soldiers and donkeys

Military Photos shows great concern about US soldiers and donkeys safety, by dimming their faces on the pictures.

Not that concern though for the safety of the local Afghan allies.
I suppose the Afghans don’t care about their life and the life of their families and relatives.
Or perhaps this is just a new kind of Islamic propaganda: „Your God cannot guard you (and that is why you are faceless), but our Allah is our Merciful Guardian.“

Or may be Americans just don’t care about any other lives except their’s.
Which one is it?
