Apart from the academic exercise, the problem is similar to fighting ants by taking out each indvidual ant instead of addressing the nest.
As I said in another thread, instead of arguing about whether it was ok to launch a missile attack to kill one al Qaeda leader, we must look at the big terrorism picture.
Saudi Arabia is supposedly an ally but is loaded with extremists that are funding terrorism and al Qaeda. Seymour Hersh reports in a New Yorker article, that some members of the royal family itself bankroll Osama bin Laden. So, we go around killing this al Qaeda individual and that al Qaeda individual, while leaving the source untouched.
Although official US policy is fight terrorism, we do very little to pressure Saudi Arabia because connected oilmen do business with them. Those oilmen don't want to jeopordize their financial interests, so, the U.S. looks the other way when it comes to Saudi Arabia. It's no coincidence that U.S. reports about funding of 9/11 and Saudi Arabian sources were redacted.

I find it unsettling that James R. Bath, George W. Bush's buddy in the Texas Air National Guard, worked as a business agent for Salem bin Laden (Ossama's brother) and that the bin Laden family and the Bush family had financial ties through the Carlyle Group into 2001.
Meanwhile, five years after the 'dead-or-alive' proclamation, bin laden is a low priority.
