While honouring those who died, it was in vein. We'd have been better of if the Kaiser had won.
World War one was a war between two Imperial Royal Houses (related) in which there was no ideological/political argument, no "bad guys" and where millions of lives lost on either side due to the folly of imperial powers.
If the UK had not gone to war with the Kaiser's German Empire, then it is probable that the Versailles treaty would not have "stolen" land from Germany, no war
reparations, no Rosa Luxemburg attempt to set up a Communist state, and therefore the "German Workers' Party" would not have been set up by Anton Drexler because there would be no grievance against the outcome of the Great War, because it would never have happened.
The Jews would not have been blamed for profiteering from that war, and would have faced no more anti-Semitism in Germany than existed in 1914.
The "stab in the back theory" would not have existed and Hitler would have been quite happy as a painter in the Austro-Hungarian empire, and he would not have joined the DAP (if it even existed), thus not turning it into the the Nazi NSDAP.
Thus no Weimar, no Holocaust, no World War 2, no Eastern Bloc beyond the USSR borders, no Berlin Wall, no missiles in Greenham Common. Also no World War 2 means no loss of UK lives in mainland Europe, no "manpower shortage" in the UK after 1945 (and no opportunity for pro-immigration lobbies/big firms to claim there was), meaning no "Windrush" and probably no collapse of the British Empire, meaning no Idi Amin and no Ugandan Asian crisis.
Less immigration and no loss of nerve means that the ruling class keeps its empire and rejects the EU. So, our present troubles can largely to traced back to 1914 and the decision to go to war with Germany and their Austro-Hungarian Allies...
And now the British Legion has a "Diversity Officer" this only adds to my belief that the wrong side won the Great War.
