Well I suppose it is progress that you acknowledge we have the advantage of knowing how bad the First World War was going to be.
the posturing gesures of imperial sabre rattling which led to the slaughter of so many disenfranchised cannon fodder in the trenches was preventable; as is the 'littkle englander' attitude which infests Torysism and is so repugnant to those in my nation who rejected it in 2016.
You still haven't answered the question I posed. Should we have reneged on our obligations to our European friends?
It's obvious from our advantageous point of view that it would have been better for us to keep out of it or, if the Germans had knocked out France in the first few months of the war (as they nearly did). But I don't think it was politically (or legally) possible for the British leaders of the time to stay out of the war.
