There was so much good stuff, I am afraid this may get missed, but I believe this was a direct shot at Kerry. Compare the story of this young soldier, severely wounded, and wanting to return to his buddies in Iraq, and Kerry.
Bears repeating. Excellent observation.
You're right! It didn't occur to me at first when Arnold spoke about the severely wounded soldier "and the list goes on and on" concerning his wounds. But the fighting ethics of today's soldier tell them to return to the unit and fellow soldiers. Not to use war wounds to get out of fighting.
