We've all spilt a glass of water at some point in our lives, or dropped a mug that's broken. The actual act of the spillage may take a couple of seconds, but the clearing up can take sixty times as long as that. If not longer.
War is like this, except with blood and bombs. The impact of the actions of aggressors or those making a genuine mistake under pressure last far longer than the initial action itself. The negative consequences last for much longer.
I've been researching the history of my local area in the Second World War recently. I now know that an area of flats near my house was built on the site of houses destroyed by a V2 missile. I imagine that those living in that street would have remembered it for the rest of their lives.
Most of the people who did the actual fighting in the war have passed on - we are now left with those who lived through it as children. The damage to their childhoods through things they did not choose to start will affect their children, their children's children and so on.
The Second World War lasted six years. Its legacy will be with us for much longer.
However, many gave their lives to stop the damaging legacy from being even worse and bringing an end to Nazism, whose plans for Europe were utterly horrific. Just the part they did do was the biggest crime in history and it is a pity that so many did escape justice - at least in this world. The right side won at the end of the day and those who claim it was not worth it are completely wrong.
May we act in ways that will prevent more death and destruction in the future.
We will remember them.
