"Because the European powers had empires obviously"
Which is all covered by what it is now known as THE FIRST WORLD WAR
All your historians have acknowledged that fact - the only qualification being in placing the blame for which of them started it.
I suggest you read Sheffield's view of the war - an antithesis of the "Blackadder Image" - which was a satirised account of the 'Poor Little Belgium"/Archduke Ferdinand assassination theory.
He said that "Britain did not drift into the war" but responded to an Imperial power stepping out of line - he was right - this is what you have been persistently told from the beginning.
The propaganda line put out by the government was that "poor little Belgium" was being raped by those "Nasty Huns" - you've been shown the posters to this effect.
The actual atrocities taking place in Belgium were grossly exaggerated to gain support for this line - you've been given evidence for this also and have totally ignored it.
The press reiterated this line because they supported the war and you are repeating it now as part of your anachronistic Jingoist flag-wagging.
There were fourteen listed reasons for recruitment - all of them relevant and none of them prominent.
The disillusionment that was rife among those both fighting in returning from the war has been an undisputed part of our literature and culture for nearly a century.
All your historians support the view that it was an Imperial War, choosing only to differ on who started it.
You have debased the memory of those who fought and died by suggesting they went "like lambs to the slaughter" on the basis of tub-thumping Jingoist (a word conjured up for the event and inseparable from WW1) recruiting propaganda.
They died in defence of a genocidal Imperialist power - disgusting and utter garbage.
You have dismissed actual word-of-mouth accounts by veterans as being "lies" or have ignored them altogether, pretending you haven't been given them.
You have dismissed the great British poets who fought and wrote of their experiences, as "romantics"
You have dismissed long-established historians such has Liddel Harte (who actually served in the war) as "revisionists".
You have written off widely-held knowledge and evidence of the war as "not being written by historians" (your carefully selected "historians" maybe).
On the basis of what? - opinions of so-called historians based on statements they have not made and opinions they do not hold or have not given.
You continue to prove yourself the rabid right-wing nutter you have now firmly established yourself as.
Far from debunking the 'Blackadder' image, you represent its most satirical caricatures perfectly "Darling".
It appears that there might be another possible series in it based on you!!
