Thanks for the ping.
You are right...they would have to change their rules. The Secretary General can not be from a country that is a permanent member of the Security Council. Would they change their rules? I don't know, but it wouldn't surprise me if they did.
Another thought...did Billy Jeff buy a home in Ireland? I seem to remember he was looking at a place there.
As an aside, he has been running all over the world undermining the Bush administration and the US, and I wouldn't be surprised if he is behind an emboldened France, Germany and Belgium.
