What we need to do now is go further... to imagine, and then create, a world without war. With the hideous death-toll in Gaza, the chaos in Syria and Ukraine, the turmoil in Libya, that might seem a long way from the reality of 2014. But the important first step is to say "this is possible", and then to start to plan the actions needed to bring a peaceful world into being.
Tonight, as we remember the point 100 years ago when the British Empire formally entered the First World War, the lamps will go out once again. Across the country millions of people will turn off the lights in their homes, businesses and public buildings, taking a moment to reflect on the dire events that were unfolding a century ago.
With World War I and its horrors so much in the public mind I wanted to share the impact that this war to end all wars had on the day-to-day life of women and children in this country through the most normal of items - a knitted sock. The formidable Queen Mary led the movement to keep our troops warm during winter in the trenches, when Lord Kitchener asked her to undertake the huge task of providing 30,000 pairs of socks for our brave lads.
The 70th anniversity of D-Day the centenary of the First World War pinpoint 2014 as a year of wartime nostalgia. Amongst fabulous stories of rebel veterans absconding from their care homes to Normandy and colourful re-enactment celebrations, one of the quieter questions being bartered around is 'do kids really know what's going on?.'
Before the Great War, Armed Forces rugby had to fight against the success of soccer - in 1906 the Army and Navy had 758 'Association' teams. A rugby Challenge match first held in 1878 was revived in 1905, became 'Official' in 1907 and an annual fixture in 1909, endorsed by no less than Admiral Lord Jellicoe...
Much recent writing on the Great War has veered between the highest-ranked and the humble: a determined rehabilitation of Haig at one end, with plain-spoken voices from the ranks at the other, whether individual Tommies who survived to tell their story, or whole battalions of 'Pals'. Lost in all this has been the story of the men arguably most responsible for British obduracy and eventual success - the officers of the line.
Lest we forget, this year marks the 100th anniversary of the war that shaped the 20th century. The first of three world wars (two hot and one cold), this conflict is remembered once a year as a lesson in human suffering, as a reminder that the war to end all wars was only the beginning of the human cost of the past century.
We should reflect on the causes and how to prevent a repeat of the massive, inhumane loss of life that the 'Great War' brought about. We should be doing that regardless of whether the number of years can make the graphics look pretty. But there are so many other conflicts that need documentaries made about them.
