Hi Chris hmm Ill have to re-listen but you do make me wonder if we didnt delvoepe that point enough. Indeed on frequent occasions, not including this interview, Brian has elaborated on the fact that communities are completely divided, people cant get to work, friends and family cant see each other, and generally speaking, the conflict these walls are supposed to resolve, do not exist or dont work the way the wall builders seem to think. There you have much of the reason for the Berlin comparison.. that walls dont solve problems. But again that may not have been delvoeped in this episode but yeah Tami has a good recommendation from alive in baghdad and while we're at it, Ill alert Brian to come respond to some comments here as well.
