Terrorism was alive before that. It'll continue to live, even if Al Qeada were wiped out. It's a tactic. You can't wipe that out. As David Cross put it, having a War on Terror is like having a War on Jealousy.
Do you see a correspondence between US presidential election years and an increase in terrorism after 2000? The graph also shows that famous lull in the years just before 2001. Maybe it's not famous to you but I remember it.

Nah, I think the spikes shortly after 1992 (Clinton) and 2000 (Bush Jr.) were just coincidences.
There's a lot of information that graph doesn't capture and I kind of regret posting it. Most of those attacks were Palestinians attacking Israel. Plus those are just the ones reported on Wikipedia, which naturally would be biased toward dates after Wikipedia's founding (in 2001).
