Christians, is it correct to rejoice in the news of the death of Osama bin Laden?

As an atheist, I do not rejoice in his death, but breath a small sigh of relief, knowing that justice, as costly as it has been, has been served. But to the people rejoicing, why do you rejoice like we have won? It is far from over. Even if the term "War on terror" weren't so broad, we still must route out the rest of al-Quida, which will take a lot of doing. I have no doubt that bin Laden has several successors appointed in case such as he is captured or killed. Where one falls, several may rise up.
