will alqaeda retaliate against the U.S. for Binladens death?

[concerned]

I have wondered since 911 what would happen if Binladen ever got caught or assasinated. I came to the conclusion that if his terrorist organization could use our own planes as missles and bring down the Twin Towers, hit the Pentagon etc... that takes possibly years of planning. I think they have to have a plan to take place for Binladens capture or assasination.
