Wartime Fun

Whilst World War 2 was a war of deadly horrors and destruction at the time and the sequelae persist to this day. However the children of the time actually found fun, enjoyment and entertainment in what they experienced and I now find it unbelievable I was one of them. Most of this paradoxical response was due to the courage and bravery of the parents and teachers of the times who shielded and protected us from the true reality of the horrendous happenings.
Now, when we thought we had at last conquered our primitive destructive impulses human kind is once again wilfully repeating the barbaric destructive behaviors against our selves that obviously remain in our collective psyches after thousands of years of so called civilization. Can or Will we ever change ?
