The First Word War, was a British/European war though. You bet your bottom dollar, Australians are going to protest being sent to fight in Europe (unless they like the hunt, then it's a whole 'nother story).

The Brits do internal confrontation, behind closed doors in private, and in negative inferences/sarcasm/irony in public.

What Brits don't do, is go against the establishment, which is what most foreigners bump into on day one. And brits have the concept of something being 'not the done thing'.

So you end up with a society that agrees on most things and has a fine line of disagreement that is invisibly negotiated...

Good luck!
