These 6th Formers just don't realise that the world outside of the UK (oh, OK, other English speaking countries as well) is Hobbesian:

True 300 years ago, true now.
They make the school boy error of assuming that everyone thinks like them in their comfortable, middle class, liberal rules-based world.
