Osama Bin Laden is dead. Terror lives.

I'm not supposed to feel happiness when someone dies, but I'll make an exception this time out. News that 9/11 mastermind and Al-Queida founder and leader Osama Bin was killed in a firefight with U.S. forces on Sunday will doubtless be greeted with endless glee around the world. After all, it's difficult to feel sadness at the loss of someone who devoted his life to killing innocents. He brought untold misery to the world, so his removal from it isn't necessarily a sad occasion.

But let's not fool ourselves. He may have been the grand poobah of the world's highest profile terorist organization. But he was - and always will be - a cockroach. A large one, but still a cockroach. And if you kill one, you've still got countless others just like it skittering every which way.

In announcing the news, President Obama said, "Justice has been done." I'm not entirely sure that's the case. There can never be anything approaching justice for the thousands of innocents slaughtered simply because they chose to go to work on that terrible day almost 10 years ago. This doesn't get them back. But it'll have to do.

We delude ourselves if we think the so-called war on terrorism is over. It isn't, and I doubt it ever will be. Terrorism remains a persistent threat. Humans retain an unfathomable ability to hate. One deranged man's death doesn't change any of this, and there are plenty of others out there perfectly willing to pick up this cretin's baton. At best, we've opened a new chapter in a book none of us ever wanted to read.
