we didn't know where nick berg was.ne of my subordinate commanders came in the office and said you need to watch this. and he put his laptop on my desk and then hit play on a video. it was, of course, the al qaeda video that had captured nick berg standing in front of a series of black-clad hooded al qaeda leaders. nick berg is in an orange jumpsuit. and then at the end of that they pull out a large knife and they decapitate him. [ screaming ] >> i was, frankly, fixated on the video in a sort of morbid kind of way because i remember my fists were just clenched up because not only are you frustrated, you're angry. >> people were always second-guessing, who actually did the beheading? i'll sit here today and tell you i believe from the nuances, the body language that we saw of the different individuals, that zarqawi was the individual who grabbed that young man by the stock of hair at the top of his head and cut his head off. and then stood there like, you know, screw you, america. >> it really brought the war to a person
