You know... if you think about it... Batman has been fighting the DCU version of Al Quaeda for about thirty years, in Ras Al Ghul and his League of Assassins.
Ras is a terrorist nobleman of Middle Eastern descent out to "purify" the world with the assistance of his worldwide network of terrorists.
Bin Laden is a terrorist nobleman of Middle Eastern descent out to "purify" the world with the assistance of his worldwide network of terrorists.
Of course, in the DCU, Bin Laden would not get very far with his group before being taken over by Ras's forces and given the choice to join them or die.
Which is my main problem with comic books that try to deal with Bin Laden: in a world where you have Ras, Kobra (or in Marvel Doom and the Red Skull), etc., and supervillains that level entire cities in a given month, something as bad as 9/11 would look relatively minor league.
