I understand your point....but comparing 9/11 and waves of nightly bombing raids not knowing if your life will snuffed out any moment...is a little different. .
Plus that was 12 years ago....and our children are being trained to not think for themselves...
I also have a friend who survived the Blitz - he was taken into the countryside where he lived in a great mansion - unlike his East End home. Sadly, as much as I love this person, he's the biggest scaredy cat I've ever met!
