Didn't they just change UNIT's name to Unified Intelligence Taskforce after they whined about it?
Indeed, which seems completely stupid, IMO. The UN didn't care about being depicted as easily being duped by the Slitheen into authorizing a nuclear attack, but showing a top-secret alien-fighting military organization within the UN is taking things too far.
Of course, what I don't get is the UNIT officer in Children of Earth even says he answers to the United Nations, and no complaint was made there. So if the Unified Intelligence Task Force still answers to the UN, then why would they change their name from United Nations Intelligence Task Force. Within contunity, I mean.
My guess is someone at the UN just doesn't like Doctor Who. Why else worry about UNIT when they clearly don't mind chanting "so say we all" in their meeting hall.
