Horseshit.
Normally on Remembrance Sunday, we remember the dead of all wars, but this one is a bit special – it’s exactly 100 years since the armistice that brought the killing phase of World War 1 to an end.
Around this time of year, there are often those who make grand pronouncements about the sacrifices those who fought made for some sort of noble goal – our freedom, the freedom of others, to defeat a really nasty enemy.
None of that applies to those who died in WW1; some of them may have felt they were fighting for their freedom (and our freedom). But they really fought because of the 19th century equivalent of mutually assured destruction.
Austria-Hungary and Serbia fought because of the assassination of a single man. Russia fought to support Serbia; France fought to support Russia; Britain fought to support France. And Germany fought because Austria-Hungary fought. This gross over-simplification happened remarkably quickly – all of the declarations of war occurred within about 1½ weeks.
So no great debate on the aims and goals of what the war was for then.
So whilst those who fought (and in some cases died) in wars are not to blame, not all wars were fought for good reasons – certainly you’ll find it hard to find a good reason for WWI.
