Celebrating in the streets is unworthy of us. So we got the guy. Good. He's done. But this is not going to end anything. There has already been ten years worth of anger built up, on top of the original cause for the 9/11 attacks. If anyone thinks those extremist groups are just going to pack up their tents and clear out their caves and quit, they are sadly mistaken.
Think about it this way. What if StoopidHead Phelps got killed tomorrow. Would other fundie groups say, "Ooh...I'm scared. Maybe we'd better quit?" You and I know the answer is not only "No," but "HELL, NO!"
So, while I feel a certain satisfaction, I can't delude myself that the War on Terror is over. Osama himself has followers who will be even more militant now that their leader has been taken out. The past ten years of blundering has created more militants than there were in 2001.
The War on Terror will never be over.
