> Perhaps that’s because most of British academia still can’t get its head around the idea that the US is now an enemy, not an ally, and that the “special relationship” is yesterday’s story.
That's a bold statement. John is using language in a manipulative way. By moving the word "enemy" into a context where it is not justified (is it really war, rather than typical negotiations?), he aims to create a dramatic perspective on a thing that is not obviously dramatic. Drama is the basis of the argument. The cases he bring up do not seem to justify the conclusive dramatic language.
