I about fell out of my chair when I read this...
Rick Santorum: en.wikipedia.org/wiki/Rick_Santorum and www.biographicon.com/view/tyrak which basically have the same information verifies that Santorum never even served in the military, let alone in war-time, let alone in combat, let alone as a prisoner of war.
John McCain has done all of the above--he was also tortured at the hands of his captors.
Perhaps we should arrange an 'exchange program', in which we hand over Mr. Santorum to a Jihadist group to be interrogated for a week, whereupon he is to be returned before addressing this situation again in stating that McCain doesn't understand torture.
Watch John McCain speak sometime, or watch him interact with people. Watch his right arm. It's disabled attributed to his time from being tortured in captivity.
