"considering that the number of civilian casualties are the pretty much the same"

No, 3553 and 2660 are not pretty much the same.

"why the big deal about the attacks on the World Trade Center?"

I think the attacks on the world trade center caused roughly 3000 civilian deaths in one day which is a bigger deal than 155 per day or 89 per day in Iraq.

Apparently you think the the attacks on the World Trade Center were not a big deal.
