In 2001 I don't even think I had a cellphone, we didnt have social media like we do now, the only source of news was the News Paper and TV.
If it happened now we would be blastered on twitter with videos / photos of it happening in real time like we are know. Much more aware of war crimes happening.
We can't change what happened in the past but I would like to think we can change the future, and Iraq doesn't happen again.
(I was living in NZ at the time still at school when 9 11 happened)
