there is dysfunction. could it fall apart and not work? absolutely. what we do know is had we not gotten to this point, we would be plunged back into war and it would be substantial. we've seen this happen before. >> president bashir is a deeply unpleasant piece of work. he'll take probably losing southern sudan as a crushing blow to his ego never mind anything else. presumably you don't have any dealings with that guy. he must loathe and detest the sight of you by now. are you worried for your own personal safety the more high profile you get? >> no. i'm not worried at all about that. honestly, i've not been brave. i'm not worried about it. the truth of the matter is the president in this situation did the only thing he could do which was help avoid war.
