You have a bitter and twisted view of the world, then joe.
Of course the world was "interested". That's why every year there are remembrance services and parades and those who were lost in the two world wars have their names called out.
"Lest we forget"
As for the service for Harold, bless him, it was not so much a public show of grief as a massive show of support for the last Dambuster who looked like he was going to his grave alone. No human being deserves that, least of all a hero.
The fact that nobody knew him is immaterial: we all owe him and everyone like him who fought in the war recognition for their efforts. Will they remember him? Well, I'm sure those adults who went to his funeral will. I read the article in the paper and I will remember him. Why would I forget?
Circus, carnival? You're a very strange man joe.
It's all real.
Well, out here it is, anyway.
