If natural is taken to mean the common sense of anything that exists in this world, a supernatural thing acting/observing in a natural world, must be natural by definition. And this is more than trick with definitions: On what does God base his decisions? It's on a what he sees, which means he is as limited by cause and effect just as everything else.

The U.S. is one of the worst in the world. Abu Ghraib was no fluke.
U.S. handles prisoners based on punishment, not help.
