We disagree, if life did not go on and we stuck our head in the dirt, then we would have not done a thing.
We disagree with what?
Let me repeat.
What I did not say is that life should stop.
What I said if that if "life goes on" is our only goal, then you have simply turned the other cheek and are doomed to repeat history.
After 9/11, life went on, but, as a country, we did things to try and stop the next potential attack.
As an example, as a frequent business flier, it was one PITA. One of my first post 9/11 flights was to Washington, DC, from Newark.
I don't know if the policy has been lifted, but, due to the shortness of the flight, we could not leave our seats for any reason....any reason.
There were soldiers patrolling the terminals with slung weapons. (The last time I saw that was in the 70's in Saudi Arabia.) Soldiers and military vehicles were all around the White House perimeter.
Bottom line, changes were put into effect almost immediately, yet life went on, as it should.
