His reason for making the film was that there had to be one totally objective film on Iraq.
Still doesn't explain the flip-flop, but I think the media is giving this guy way too much gravitas. But, then again, they are desperate for ratings... and Ritter is probably good for that.
Plus, to Ritter, the publicity is good. If, he thinks (my opinion only) he can be the savior of the world, then I guess publicity is necessary.
