Yes the Great War was a continuation of British foreign policy of the last 500 years. I think the Germans would have had their hands full intergrating their EU that the UK would have been allowed its slow decline in peace.

I really do think the Great War broke the long slow march towards democracy and moderation that had started in the 19th C. Germany in the early 20th C was the centre of modernisation and Liberalism and if it wasn't for the war there is nothing to suspect that this wouldn't have continued.
