The causes of the First World War were superficially about the ties and treaties that have been mentioned above. In reality they were more about the preservation of Empire. The rise of German power as demonstrated by the growth of its navy and army threatened Britannia's rule over the waves and the acquisition of territory in Africa and elsewhere. This assassination of Archduke Ferdinand and the alliances provided a legal framework which, since they could have been ignored if chosen, proved about as worthy as the causes for invading Iraq in 2003.
The subsequent loss of 10,000,000 lives through the absence of political courage is a stain that should not be removed from our consciences.
"And all this madness, all this rage, all this flaming death of our civilization and our hopes, has been brought about because a set of official gentlemen, living luxurious lives, mostly stupid, and all without imagination or heart, have chosen that it should occur rather than that any one of them should suffer some infinitesimal rebuff to his country`s pride". Bertrand Russell 1914.
I think the national war memorial on the Western Heights would be a fitting tribute and I would also agree with Neil that November 11th should be a day of remembrance.
