"When one forgets history, one is then domed to repeat it."

I am not sure where you are going with this. What is it that we must remember? That there was an attack, and many people died and their families grieve? I think that goes so completely without saying, for 9/11 and for all other terrorist attacks around the world. It is unspeakable, just as with other murders or other kinds of senseless violence.

But what is it that we must remember? To be always suspicious? To be ready to retaliate? To never discuss why this happens? To keep up the war on all muslims?

What I am trying to say is: the dust has settled. I just think it is time to learn from this.
