Terrorist victims in 2001: 3,000

That's not entirely true. There were ~3000 terrorism-related deaths, but the point of terrorism is that it victimizes an entire society by creating a culture of fear and uncertainty. That's what differentiates terrorism from (conventional) murder.

To "create a culture of fear and uncertainty" is certainly the aim of terrorism. However, its effectiveness is dictated by the reaction of the affected population, not by the perpetrators or their actions.
