Some wars are inevitable: WWII simply had to be fought and won. The Great War, or World War I, was different. There was no moral superiority on either side of the conflict. Germany, Britain, Austria, France, Russia, all belligerents were one civilisation. Europe was on the path of self-destruction with no good reason.
Today, Europe is only superficially peaceful. There is a real, albeit limited, war in the Eastern Ukraine. Israel, a European country located in the Middle East, is under a constant threat. Europe herself has her own breed of fanatic enemies, who are determined to destroy her culture and civilisation.
We, modern Europeans, are peaceful people. It is much better than being bloodthirsty, but our passion for peace has made us complacent and perhaps even unwilling to defend our civilisation. However, we must defend it. It's our duty. The European civilisation is not our property; we merely look after it for the next generations.
There's no guarantee that the superficial peace of our times will last forever. It is, in fact, highly unlikely. We, Europeans, are one civilisation, which should not waste its limited powers on internal conflicts. This is perhaps the most important message of the mournful year of 1914.
Lest we forget.
