The Second World War is something I am far too young to remember - I wasn't even born for the Falklands War. I have never been shot at, never seen an active battlefield except on a screen and the closest I've ever been to a theatre of conflict was flying 35,000 feet above Iraq on a holiday to Dubai.
Yet, people my age 70 years ago were frequently faced with mortal danger. Someone like me would have been sitting in a tank in the Egyptian desert, trying avoid the ending of my life in burning agony, while trying to inflict said agony on a bunch of Germans subject to the whim of a megalomaniac.
The tragedy of war is not just that that sort of things happen - it's that on occasion, they're the least worst option.
We will remember them.
