he served in afghanistan as adviser to general david petraeus. mark, i'll begin with you. you worked on some of these issues with petraeus in the bush administration. in iraq, let's just take the example of iraq, not even talking about taliban. in iraq, all of that was conducted under the normal laws of war. there were insurgents who tried to kill american troops, who blue up marines with ieds who were released back, am i correct? >> if you take a look back at the arguments during the early phase of the iraq war, there are going to be people in conflict who do bad things. look even further back, this is when larry was at the state department, take a look at the arguments over the taliban and al qaeda. there were nazi ss officers during the second world war who were treated as prisoners of war. if they were war criminals, tried and in many cases executed.
